Function
The M101 allowed personnel to practice with the external shape and handling of the M100 without an explosive warhead. Its reusable body and replaceable standoff rods supported repeated training. This gave units a dedicated practice item for learning the equipment associated with the GREM door-breaching role.
Documented End-Item Application
Army ammunition data sheets identify M16-series rifles and M4 carbines as the parent weapons for the M101 GREM-TP.
Product History
The M101 was documented in Army ammunition data sheets by November 2002. Change 4 to TM 43-0001-29, dated 22 November 2002, added its dedicated pages 4-17 and 4-18. These describe a reusable training design with replacement standoff rods. In August 2014, military performance specification MIL-PRF-32501 formally covered both the M100 GREM and M101 GREM-TP.
Parent-Equipment History
The M101 was developed for the established M16/M4 small-arms family. The M4 evolved as a shorter, lighter version of the M16 and entered service in 1994. GREM added a specialist entry-munition role to these existing weapons, with the M101 serving as the training companion to the service grenade.
Weapon-System Background
The GREM family grew from Rafael’s SIMON rifle-launched entry munition. In October 2002, Rafael announced completion of the U.S. Army’s type-classification process for the GREM derivative. The system addressed the need to breach doors while reducing the exposure involved in approaching them directly. The M100 filled the explosive service role, while the M101 supported preparation and practice.
History of Use
Official Army footage dated 11 April 2006 records Soldiers testing GREM at Tikrit, Iraq. Released by the 3rd Brigade Combat Team, 101st Airborne Division Public Affairs office, it documents familiarization and test firing during the Iraq War. The M101 belongs to the training side of this system, giving personnel a reusable, nonexplosive counterpart for practice.
