There was a topic about TRUK few weeks ago. Lots of useful information, but I especially checked captured equipment numbers for land troops (page 40). Except mysterious 56 Automatic Pistols for IJN (there is picture attached, and those are clearly some version of MP18)...
Take a look at list of IJA equipment. There is incredible amount of support weapons:
The number of Rifles is 12186, which roughly corresponds to number of soldiers, there are 1313 pistols, which also seems OK, but...
There are 1131 "knee" mortars. Almost 1 per 10 Rifles, and those rifles should also be used by all support troops, gun crews, etc. This seems almost, like all troops were line infantry!
Then... there was 1192 Rifle Grenade Launchers - that is like 2 per squad! And the mysterious 475 Type 2 Grenade Dischargers (they are either "knee" mortars "Kiska type", or Type 2 Rifle Grenade Launchers for AT grenades, which increase number of such devices to 3 per squad!).
Also number of MGs is large. 792 LMGs, and 400 HMGs (not even counting AA types). My rough estimation of composition of forces (counting men) indicates on less, than 500 squads in all IJA units. So again like 2 MGs per squad.
Is this example of mysterious Island Warfare Units? Seems quite early, as first unit arrived on Truk in January 1944.
I also wanted to add Asahi repair ship, but its story seems complicated. It was Battleship, and during conversion they supposedly somehow removed its armor.
First it was converted into submarine salvage ship (so maybe AS), then plane catapult was added. Later it served as transport, then it was converted into repair ship (AR?), but six months later it was modified into torpedo depot ship (so like AD?), but it was repairing CLs, and I do not think ADs can do that. So what will it be? Repair ship with rearming ability? Any ideas?
