The US DOD should issue the "Ranger Anti-Armor Weapon" (The Carl Gustaf 84mm M3/M4) as a general infantry weapon.

Infantrymen want a weapon of this type, which is re-loadable with various munition sub-types and does not force the expenditure of costly, cumbersome, heavy, guided weapons which are tasked for other purposes (namely, anti-MBT warfare, etc). SEE: https://youtu.be/US2DQnU1lhE
