US Army's "comparative" trials of
Firepower for Strykers:
30mm Autocannon
vs
12.7mm Machinegun
US Army's Stryker 8x8's has been armed with a remote weapon station (RWS) with a .50cal (12.7mm) M2 machinegun.
Sometime ago I've heard that US Army is considering up-arming the Strykers, or at least a portion of the fleet, with a weapon system that has more bite than the .50cal.
The turret that has been selected for consideration is the Kongsberg's 30mm Remote Turret MCT30 armed with 30mm Mk44 and a 7.62mm machinegun as coax.
The following YouTube video is an excerpt from this effort.
However, it is a little bit funny to even demonstrate the capabilities of such diversely different weapons as the .50cal and 30mm.
I won't even go to the details like muzzle energy or penetration and just will post the image below. One image is worth thousand words as they say...
Here is an image with the Kongsberg turret on Styker:
Here is the video I've mentioned:
As the soldier in the video says:
"Don't bring a knife to a gunfight. That's kind of what this is... Give me a 30mm to fight and it's over!"
