Cartridge for Vlug[]
I can tell the ammunition Type of StA25 Vlug happen to be 5.56x45mm, it's a rifle cartridge, since I managed to figure it out and never thought the answer for the cartridge was, since I looked closer the drum magazine, it look appear to be rifle bullets. Ever since the end of Killzone 3, when most of the older guns includes the StA-11 was replaced and been given or sold to mercenaries or keep by veterans.
Similar to MGS's The Patriot and even Wolfenstein's SMG , since it's caliber is .30 carbine. Which means it chambers rifle ammunition. (Czarjoseph.demaisip (talk) 10:38, January 22, 2020 (UTC))
