Ranger was used in filming, standing in for the Enterprise) in the scene where Pavel Chekov (Walter Koenig) is captured, and again when he falls and injures himself trying to escape.

Remington 1100

Seen in the hands of Marines on the Enterprise of 20th Century are several Remington 1100 shotguns, almost an equal amount of these along with the M16A1's as shotguns were and still are popular with security units in the U.S. military, which is one of the main roles of the Marines aboard ships. They feature a bayonet lug at the end of the muzzle, as well as a woodland camouflage sling that doubles as a bandolier holding a large number of spare shotshells.
