The HMMWV’s GRS was frst felded without the swivel design, causing gunners
to get tangled. Since it didn’t have the quick-release button, gunners couldn’t exit the
vehicle quickly. But now that’s changed.
IF you see an adjustable tail strap with a push-button quick release and swivel,
you’ve got the improved gunner’s restraint system. The quick-release button lets you
get out oF your MRAP quickly without having to drop the harness frst. The swivel
keeps the tail strap From twisting. And the adjustable tail strap lets a tall gunner
lengthen the straps For easier access. It also allows shorter gunners to keep the strap
tight enough to protect them as it should.
