Sorry I should have supplied a couple of reference sites for you to peruse. You’ll find the M4 SOPMOD accessory kit well documented here (towards the bottom of the page): http://www.isayeret.com/weapons/assault/m4/m4.htm Ural Troop Carriers: http://www.uralaz.ru/LANG=en/ural432031.html LAW Launcher. This has an excellent section linked at the bottom called OPERATION AND FUNCTION. This should take care of any training issues for those of you who are only familiar with RPG’s. http://www.globalsecurity.org/military/systems/ground/m72.htm
