Terminal Learning
Modern battles occur anywhere in the world, under various battlefield conditions. With more of the world becoming urbanized, we as soldiers can expect to find ourselves fighting door to door in a city instead of a jungle environment or forest. Being able to gain a foothold in a building as quickly as possible can mean the difference between success and failure of the mission.
At the completion completion of of this lesson lesson you [the [the student] student] will: Qualify with the RLEM/RLEM-TP. Given an M16A2/A3/A4 or an M4 series rifle, LBE, Kevlar, BLPS, flak vest, gloves, a door attached to a frame and/or building, 1 RLEM-TP with 5 standoff rods, 1 RLEM, 1 round of 5.56 ball (M855/M856) ammunition (RLEM), 10 rounds M195 grenade blank cartridge per soldier. Put the RLEM into operation and engage each door within 1 minute. Must engage 3 out of 5 doors from various angles and positions using the proper aiming point for the range selected IAW this TSP and TM 9-1330-210-12&P.

When firing the RLEM, use only M855 ball or M856 tracer ammunition. When firing the RLEM-TP, use only M195 grenade cartridges. All personnel within within 8 meters of target must have double ear protection. protection. All personnel beyond 8 meters of target must have single ear protection Gunner must wear helmet, BLPS (Ballistic Laser Protective Spectacles), flak jacket, gloves, and rolled down sleeves. All non-firing personnel within 40 meters of target must have protective clothing, or be under or behind cover. Do not use a damaged munition. Weapon must be in SAFE position before installing munition onto weapon. Gunner’s position must be at least 15 meters away from target. RLEM must not be fired less than 14 meters from target. Extended eye relief, with optics or iron sights, must be used when firing. RLEM is a high recoil munition. When firing from shoulder, rifle buttstock should be pressed against shoulder. Do not touch an unexploded ordnance (UXO). Recoil pad must be properly attached to M4 before firing RLEM to avoid injury to personnel or damage to buttstock. Standoff rod must be attached before firing the RLEM. Weapon must be properly a imed and munition fully seated against weapon muzzle before squeezing trigger. When putting RLEM on muzzle, keep weapon muzzle pointed up and towards target. The firing of a defective RLEM is not allowed. Keep live (explosive) RLEM separate from training (non-explosive) RLEM-TP. Do not mix M195 blank grenade cartridge with M200 5.56 standard blank ammunition.
NONE
At the completion completion of of the classroom classroom instruction instruction and practical exercise exercise (PE), (PE), you will receive a performance evaluation and a twenty question written test during which you must receive a go and score a minimum of 14 out of 20 questions in order to pass.
Gaining the initial foothold in a building is very critical and can be very difficult. The RLEM will allow for a complete breach of main entrance doorways while maintaining a safe standoff distance for the breaching element. The detonation of the RLEM will not only confuse the enemy but can cause injury to anyone in the vicinity of the door being breached allowing the assault element to gain the critical initial foothold on the building with more speed and precision.
NOTE: Prepare your slide with the characteristics of the RLEM.

ENABLING LEARNING OBJECTIVE A
TRANSITION:
Our primary objective will be to acquire the skills needed to mount and operate the RLEM on an M16A2, A3, and A4/M4 series weapons. Before we can effectively engage targets using the RLEM, it will be necessary to familiarize yourself with the RLEM system and subassemblies.
NOTE: From this point on any reference to the M16 will include the M16A2/A3/A4, and any reference to the M4 will also include the M4/MWS and M4A1.
Conditions:
Identify Characteristics of the RLEM/RLEM-TP. Classroom environment with student hand out. Identify the six main parts of the RLEM IAW this TSP and TM 9-1330-210-12&P.

a. Description and function of the XM100 RLEM and XM101 RLEM-TP The RLEM is a rifle grenade with a warhead designed to breech doors (Figure A1). It is mounted on a soldier’s M16A2/A3/A4, and M4 series weapon. The RLEM is launched, launched, by firing a standard 5.56 mm round , to a distance of at least 40 meters . It is designed to break down a door and allow soldiers to enter a building with minimum hazards.
Figure A1: RLEM

The RLEM-TP is a training munition (Figure A2). The RLEM-TP is an aluminum tube, which is similar to the RLEM in its weight, aerodynamic structure and operation. Each RLEM-TP body can be reused as long as the round has no major damage except for the stand off rod, which must be replaced after each firing. A M195 grenade cartridge is used to fire the RLEM-TP in order to prolong the serviceability of the RLEM-TP during training exercises. The RLEM-TP comes in a kit that includes 20 RLEM-TP bodies, 100 standoff rods, and five extracting tools, which allows multiple firings of one RLEM-TP body. The standoff rod should be replaced after each firing.

FIGURE A-4: Main Parts
1) Standoff Rod: The standoff rod (Figure A-5) screws onto the front of the warhead. It is made of a 15.75 inches length aluminum tube, with an aluminum disk (button) on its end. The rod is designed to initiate the fuze, which subsequently
9
initiates the warhead at an optimal distance (15.75 inches) from the target therefore directing the maximum amount of energy towards the door. The standoff “button” serves to prevent penetration of the rod into the door, which would reduce the maximum maximum amount of energy directed towards towards the door. The stand off rod maintain maintains s an optimal optimal distanc distance e between between the warhead warhead and the door, thus ensuring full affectivity of the explosive charge, which generates a pressure cone for breaching of the door.
Figure A-5: Standoff Rod 2) Warhead: Warhead : The warhead (Figure A-6) consist of a plastic envelope (1) containing 120 grams of PBXN-109 cure-cast explosive (2) covered with a plastic cover (3) to eliminate debris being thrown back towards the operator. The standoff rod is threaded into the front of the warhead. The explosive charge is initiated by a PBXN5 pellet (4), which ignites the detonation from the detonation cord of the pyrotechnic adapter.
Figure A-6: Warhead 3) Pyrotechnic Adapter: The pyrotechnic adapter (Figure A-7), located between the fuze and the warhead, is used to transfer the detonation shock between the fuze and the warhead. The special structure of the adapter provides an extra safety element to the gunner by preventing the tail section being blown back towards the gunner
10
after being fired. The adapter contains aluminum and plastic casings and a detonating cord. The detonating cord is a 15 grain cord with two PBXN-5 pellets in its sides. The pellets contain 80 mgr. and 170 mgr. explosive.
Figure A-7: Pyrotechnic Adapter
4) Fuze: The fuze is based on mechanical mechanism and initiation train. The initiation train contains a primer located in the rotor. The fuze has two safety features: direct bullet impact and acceleration. Upon firing, when both features exist, the rotor is released and free to rotate to the “ARM” position. In the “ARM” position the firing pin and the primer are in line. Upon hitting the target, the firing pin hits the primer, which ignites the detonation cord all the way to the warhead (Figure A-8).
Figure A-8: Fuze
5) Bullet Trap Device: The bullet trap (see Figure A-9) is mounted in the forward section of the tail tube, behind the fuze. It is designed to stop the bullet and absorb the bullet energy. The bullet trap consists of a housing, steel trap, bullet diverter and three steel disks. The bullet diverter is an additional safety feature in the RLEM, which is intended to guide the bullet away from the warhead in the unlikely event that the three disks and bullet trap are defeated.
11
Figure A-9: Bullet Trap 6) Tail Section: The tail section’s primary function is to stabilize the round while in flight, and it is the portion of the round that slides over the barrel of the weapon (Figure A-10). When inspecting the RLEM, if any of the tail fins are damaged the grenade must be replaced. The RLEM-TP can be fired with minimal damage to the tail fins.

ENABLING LEARNING OBJECTIVE C
Transition: Before conducting a successful breach using the RLEM, the firer must be familiar with the different types of doors, their characteristics, and the RLEM’s ability to breach the door. NOTE: Prepare your slide with the characteristics of doors.
Conditions:
Identify Characteristics of different types of doors. Classroom environment with student hand out. Identify all four components of a door and the four door types IAW this TSP and TM 9-1330-210-12&P.
Learning Step/Activity 1: Characteristics of doors. Method of instruction: LECTURE Instructor to student ratio is: 1:40 Time of instruction: 15 min Media: Computer with infocus projector and Handout. NOTE: NOTE: The RLEM will be used to engage exterior doors only. a. General. There are many different different types types of doors. The The door door types encountered encountered depend on location (rural area, city, abandoned areas and make-shift), and their design (main entrance, safety door, fire door, or inner door). The RLEM is designed and most effective against main entrance doors because of the way they are constructed. This does not mean that RLEM is less capable against other door types. This chapter will concentrate on several different door types.

c.
Doorframe: The frame is a group of wooden or metal parts that when assembled form an enclosure and support for the door. The doorframe is what determines which way the door swings open. Hinges: These are the assemblies that attach the door to the frame and allow it to swing open. The upper hinge supports greater forces than the lower hinge. The bigger and heavier the door is the more hinges will be used. Handle: The handle is located at the opposite side of the hinges. When turned, it opens the door. Lock and Bolt assembly: They are located under the handle. When the door is locked, the bolt enters into a recess in the doorframe. There are several different types of bolts. Some are single metal rods and others are multip multiple le metal metal rods. rods. Some Some doors doors can have have sever several al bolts bolts in differ differen entt locations such as at the top and bottom of the door and even on the hinged side of the door. All installed bolts are opened or closed by a central locking mechanism that is located near the door handle.
Door Types . There are four types of doors that concern infantrymen. 1. Metal Doors. Metal doors are usually heavy and have a metal frame and metal
rods rods inside inside of it. The The rods rods provid provide e the door with with stren strength gth and flexib flexibili ility ty in response to stresses. The RLEM causes the metal door to buckle inward and dislocate from the doorframe. 2. Wooden Doors. Wooden doors are constructed in three ways. They are solid, have a pressboard center, or a honeycomb center. The RLEM affects all wooden doors the same way. The doors are broken up into several pieces upon explosion.
Dual-panel doors have two door panels that are opposite 3. Dual-Panel Doors. Dual-panel each other. They either have one panel that cannot open or both panels swing open. The effects of the RLEM on dual-panel doors depend on the material of the door. Fire the RLEM towards one of the two panels if the doors are made out of wood. If the doors are metal, fire two RLEM towards the door to make sure the dual-panel doors are breeched. recommended to use RLEM against Emergency 4. Emergency Doors. It is not recommended doors. Emergency doors open outwards to allow easier and faster exit from a room. When a RLEM engages and explodes against this door type, the hinges and bolts could bend and get stuck jamming the door into its frame.

a.
Aim Points Points. The most vulnerable point should be chosen when engaging a door with the RLEM. In the majority of cases where the door is still intact the vulnerable point is typically the door center, so the point of impact for the RLEM should always be the door center or towards the locking mechanism if its location is known. This also applies when engaging dual-paneled doors. In order to achieve a hit at the point of impact the weapon should be aimed to a point about 16 inches above the desired point of impact when the firer is at a distance of 15 meters. At other ranges the aiming point is adjusted due to the ballistic trajectory of the RLEM.

WARNING Prior to SQUEEZING the trigger (SPORTS), ensure the round is fully seated and the weapon is re-aimed towards the target.
a. Weapon Misfire. If a misfire misfire of the the weapon weapon occurs, occurs, maintain maintain the weapon at an upward angle and apply sports IAW TM 9-1005-319-10, M16/M4 series Operation Manual.
WARNING Never touch or approach an UXO, contact EOD for recovery and disposal.
b. RLEM Misfire Misfire. If the RLEM impacts impacts the target and does does not explode, then the the round must be treated as an Unexploded Ordinance (UXO), contact EOD immediately. c. Weapon fires but but the RLEM RLEM is not launched launched (Hangfire) (Hangfire). If the weapon fires but but the RLEM does not leave the barrel place the weapon on safe and place the weapon on the ground. Do not attempt attempt to separate the RLEM from the rifle. Since one of of the safeties in the RLEM has been deactivated then the munition must be treated as an UXO contact EOD for proper disposal. NOTE: Conduct a check on learning and summarize the enabling learning objective. Q. What is the designated designated aiming aiming point if engaging engaging a target target that is 15 meters meters away?

TRANSITION:
Before a soldier should be allowed to fire the RLEM the soldiers needs to complete a qualification course so that he is able to demonstrate the skills necessary to properly and safely employ the RLEM.
Conditions:
Qualify with the RLEM/RLEM-TP Given an M16A2/A3/A4 or an M4 series rifle, LBE, kevlar, eye protection, flak vest, gloves, a door attached to a frame and/or building, 1 RLEM-TP with 5 standoff rods 1 RLEM, 1 round 5.56 ball (M855/M856) ammunition (RLEM), 10 rounds M195 grenade blank cartridge (RLEM-TP) per firer. Put the RLEM into operation and engage each door within 1 minute. Must engage 3 out of 5 doors from various angles and positions using the proper aiming point for the range selected IAW this TSP and TM 9-1330-210-12&P.
Learning Step/Activity 1: 1: Method of instruction: LECTURE Instructor to student ratio is: 1:40 Time of instruction: 15 min Media: Computer with infocus projector and Actual equipment
a. Range Set-up for the RLEM-TP. The number of firing points will be determined by the amount of firers available for training, range size limitations, and available resources. b. Targets. Targets can be actual doors, if available, or 1-inch plywood can be used. Target frames should be constructed to allow for stabilization and easy replacement of new targets. Each target will be stationary and placed 10-15 meters apart from each other, this will allow for each lane to have enough room to fire at different angles to the target (Figure D-1a). Each target will have a 12-inch circle drawn in the center of the door; this circle is the designated point of impact.
NOTE: NOTE: As soldiers become more proficient with the RLEM/RLEM-TP additional challenges may be introduced, such as increasing the angle to the target (not to exceed a 20 degree angle), or conduct training during hours of limited visibility. c. Firin iring g La Lanes. Each firing lane will have at a minimum 5 firing positions; one at 15 meters at a 90 degree angle to the target, 2 at 20 meters with 1 at 75 degree angle left and 1 at 75 degree angle right of the target, and 2 at 25 meters, with 1 at 75 degree angle left and 1 at 75 degree angle right of the target (Figure D-1a). Firing lanes can share left or right firing points as long as all firers are synchronized while firing. Firing position can be constructed with obstacles that will provide the soldier with cover. This will allow the solider to decide on a proper firing position based on suitable cover. d. Conduct. At the beginning of training each solider will be made aware of the safety requirements for the RLEM/RLEM-TP. The first firing order will start at the 15 meter firing position, and each lane will have a safety (FigureD-1a). All firers
24
will be firing at the same time. At each firing position there will be 1 RLEM-TP and 1 standoff rod. Once the command is given to fire, each firer will assemble the standoff rod to the RLEM-TP, slide the RLEM-TP over the barrel of the weapon and then engage the target using the proper offset, all within 1 minute. The impact of the RLEM-TP must impact within the 12 inch drawn circle in the middle of the target to be considered as a hit. Once all firers are done they will move (at the same time) to the 20-meter left (right) angle position and repeat everything that was done at the first firing point (Figure D-1b/c). Complete the same procedures for the 25-meter target as well. A soldier is considered qualified if 3 out of 5 targets have been successfully engage in the allotted amount of of time. A practice record fire and record fire will be conducted. Once the soldier has qualified he should be given the opportunity to fire an RLEM at an actual door to see the effects of the munition.
