Detailed breakdown of ammo load for

7.5cm IG
15cm IG
7.5cm PaK
12cm Mortar

This is an actual strength report so not a KSTN, but it does show that

7.5cm IG is probably somewhat low, difficult to say since the platoon is badly understrength, but with only 12 rounds on the gun carriage, it heavily depends on how many many platoon wagons would be available at full strength.
15cm IG the 10 rounds in game is too low, as there are 12 rounds on the gun carriage alone, and another 33 rounds on platoon wagons. Even with the second gun missing, it seems 20 would be a more realistic load.
12cm Mortar probably ok as here there are 35 rounds per mortar.

7.5cm Pak is too low, as there are 27 rounds on gun carriage alone
