Mild punch? That’s pretty heavy for a troop carrier!
If it was true, but it's not. The Stryker's Norwegian-designed Remote Weapons System mounts Either a M2 .50 Browning machinegun, common on US troop transports since the WWII M3 halftrack and the M113 tracked APC of the 1960s-'70s, OR the 40mm Mark 19 grenade launcher, not both. A turret fitting both weapons was a feature of the Military Polices 4-wheeled Armored Security Vehicle, [ASV] ordered cancelled lest its success overshadow Stryker's questionable future.
In live-ammunition weapons testing with the RWS, the .50 experienced repeated ammunition belt hangups and stoppages resulting in bursts of 45 rounds or less before the operator had to expose himself and come out of the hatch to clear the jam. One Stryker crewman has told me that the RWS sighting arrangement won't stand up to the recoil of the 40mm launcher, and that re-sighting the unit even when the .50 is used is a daily task.
The problem here may not be the Stryker itself but the weapons subsystem used aboard it, of which several possible workarounds might be possible. One of the most immediately obvious would be the combined weapon turret of the ASV.
