so I managed to have my first promotion and a interesting feature I discovered,
my guardsman had the Flying armor and when I promoted him then this armor "vanished"
I given him carapace/Hellgun and then I saw I can promote him to officer and I chosen to
do so as the officer chainsaw is good stuff for the commisars...and after the promotion also the hellgun armor was gone.
so it seems after a promotion the equipped armor vanishes..but not an issue can produce them again
also the fact that I can buy at the trade place tygrus or ultra bolters and kraken ammo...well I own the enemy so hard
(especially the scoped bolter with a commissar of aim 90+ and anti armor ammo..kills even chaos marines easy, well I did use it also when I played as the Marines...only that I could not buy it which is very helpful)
