THE BULLETS RICOCHETED OFF THE INSIDE OF THE OGPK, STRIKING THE SHOOTER AND, IN SOME CASES, VEHICLE PASSENGERS.
THAT'S A FANCY WAY OF SAYING THE SOLDIER COULD SIGHT THE TARGET CLEARLY, EVEN THOUGH HIS RIFLE'S MUZZLE DIDN'T CLEAR THE TOP OF THE OGPK.
* Don't fire individual weapons from the OGPK if at all possible.
You can't use the OGPK, but you can use the gunner protective kit (GPK), NSN 2510-01-532-5221.
OGPKs are approved for use only on long-term armor strategy (LTAS) FMTV models.
OGPKs haven't been tested or approved for use on LSACs.
However, these integration kits do not let you put the LRAS3 on vehicles that have the OGPK
overhead armor protection.
