Star Trek Into Darkness
The following weapons were used in the film Star Trek Into Darkness:
Mk 19 Grenade Launcher (mocked up as futuristic weapon)
When John Harrison attacks the conference room in a Federation "jumpship", a few security officers attempt to use some sort of futuristic mounted grenade launcher against him. This appears to be a Mk 19 Grenade Launcher mocked up as a 23rd century weapon. It is unclear if this weapon is supposed to have the same capabilities as a grenade launcher, as they are only seen firing one shot before Kirk takes down the vehicle with some improvisational thinking.
