Description

I'm pretty sure ammunition costs are off for training munitions for certain ammo. SRM6s are the only one I've seen, but could be more if I'm not missing something here. Using CampOps rules, training munitions should cost a quarter of the capacity of the unit. MegaMek and Techmanual concur on the cost of a ton of SRM6 ammo, which is 27,000 C-bills. Following this, the monthly training munitions cost for a 'Mech that carries two tons of SRM6 ammunition and nothing else would either be 13,500 C-bills if we're being abstract or 14,400 if we're counting individual shots, rounding up. This is the monthly cost I get for an unmodified Javelin JVN-10N and nothing else in hangar:

The main cause for this was fixed in #3486 (parts cost multiplier)

The bugged SRM 6 ammo... no idea. It only affects SRM 6 ammo in this instance even though the getStickerPrice() function was pulling the correct value.
