Absolutely wild detail given to the guns.
pg 11 - HK G3SG/1.
pg 16 - Type 99 Arisaka with AA sights.
pg 18 - the type 99 again, an AR pattern with a eotech holographic sight and angled foregrip, and what appears to be a tactical thompson or at least is using a thompson mag. Also a tactical beretta 1301 with vent rib.
pg 30 - some kind of mossberg but I’m drawing a blank on the rifle. I’ve seen it before and thought “my gooodness, they literally couldn’t have fit more picatinny rails if they’d tried”
pg 31 same type 99 and a type 94 nambu.
pg 32 looks like Daewoo AR 100
