The M134 heavy machine gun is the main armament for the UH-60 Blackhawk.
The M134 is a very powerful weapon with a good rate of fire and lots of power.
With good accuracy it can take out light tanks, APC's, and troop transports with a several second burst.
Against infantry, with high rates of fire and accuracy, can take an entire platoon out in mere seconds.
After about 15–20 seconds of continuous fire it will completely overheat and be unusable until it cools.
