Guards - 2 PTRS and 2 DP after reinforce.
Paratroopers - 6 thompsons after reinforce. Their 2 grenades can destroy wooden house, 3 grenades can destroy middle house on Feymonville. 35 munition.
I haven't made exhaustive tests, but Guards PTRS duplicate. Either you don't upgrade, lose models and now you have 4 PTRS, or you drop a PTRS/DP and then duplicate PTRS.
Sure about Thompsons? When i test it they remain with 4 of them.
