I'm not sure there is a newer version of FM 7-11 than the 1962 revision... I can look around my armory for a hard copy, but FM 7-11 is no longer "current" and is not available on AKO (Army Knowledge Online). Are you looking for an M113 based TO&E for a specific time period? During the 60's and 70's the M113 mech companies had 3 M125 81mm mortar carriers in the company mortar platoon plus 1 M113 for the FDC. These seem to have been dropped at some point, because a more recent M113 mech unit (Massachusetts Army National Guard) did not have mortar carriers at the company level. I think the unit had 3 81mm mortars, but they were not mounted in carriers. The only SP mortars were the M106A1 4.2" mortar carriers in the battalion mortar platoon. This was 1998-2000 time frame. Post 2000 the unit converted to a light infantry TO&E and was probably one of the last M113 based mech infantry battalions in the US Army.
