I had no idea that there was a wide variation. Say '45, Pacific, Iwo. This should include most lessons learned.
The different theaters required different equipment and new equipment was added as it became available so the TO&E was always evolving. Until mid '43 the Marine Div TO&E closely resembled an Army Division. 1943- 14,253 Offs & men 243 BAR 157 medium MG 236 Heavy MG 90 60mm Mortar 54 81mm Mortar 557 Bazooka 57 57mm AT guns 54 105mm Howitzer 12 155mm Howitzer 5 half tracks 2000 vehicles 3 infantry regiments each comprised of 3 battalions 1 AT company 1 Canon company 3 light Arty battalions 1 medium arty battalion 1 Engineer battalion 1 signals company 1 recon troop 1944- 17465 Offs and Men 464 medium MG 161 Heavy MG 267 Flamethrower 117 60mm Mortar 36 81mm Mortar 172 Bazooka 36 37mm AT guns 12 75mm AT guns 24 75mm pack howitzer 24 105mm howitzer 46 M4 tanks 1050 vehicles 3 infantry regiments comprised of 3 battalions each 1 tank battalion 1 weapons company 1 arty regiment comprised of 4 arty battalions 1 engineer battalion 1 pioneer battalion 3-4 amphibious tractor battalions will be attatched for an amphibious landing
Well, if no one else knows.....I'm not sure, but something like Transport, ordanance, and equipment? I know how it's used in context, but haven't gotten an exact definition.
