Nikolai with an AKM, duster cover off (the AK74U or the AK-74 with a light stock from bo6 likely woulda fit better but i like the beat-up look of the “cursed” kastov 7.62 better)
Dempsey gets the SO-14 with the 1957 stock, the trench wrecker marine sp & the XM4 (M16) (woulda given him a m16 with the grenade launcher or an m60 but i like the look of the base heavy stock & long barrel, plus there is no m60)
Richtofen the MP40 & the Model L with the warriors blood blueprint (to make it look like an STG44) that unfortunately doesnt appear on his back
