I’m probably just stupid, but why is it significant they’re armed with “standard” weapons?
That they will be used as standard infantry. If they would be guards or non combat they would get worse gear. As specialized soldiers, they would get tanks, artillery or whatever. Also it is Russian gear and not North Korean.
In other words they will be used for human wave attacks.
I think it shows that they’re taking on standard combat roles. The alternative could be them strictly filling non-combat roles, such as logistics/cargo transportation or engineering-type work like building trenches and other fortifications.
You get a rifle, the next man gets the ammunition. When the man with the rifle dies, pick up the rifle and load it, so the next man who grabs it from your cold, dead hands can shoot it.
