Norwegian armor crewmen with pintle-mounted MG3A1. MG3 rate of fire is still as phenomenal as its MG42 predecessor, clocked at circa 1,150 rounds per minute. (MG42 clocked between 900 and 1,500 rounds per minute).

At such firing rates and vibration, relative accuracy can be attained via stable platform, out to 200 meters via hand-held, 800 meters via bipod, and 1,200 meter via tripod.

Ammunition comes in 50-round to 100-round non-disintegrating belt, but can be coupled together into drum magazine for sustained-continuous fire.
