Under Siege is a 1992 action film which could be summed up as "Die Hard on a battleship". In the film, Navy SEAL turned cook Casey Ryback (Steven Seagal) battles terrorists who have taken over the battleship USS Missouri. It was directed by Andrew Davis, who would later direct co-star Tommy Lee Jones in The Fugitive. Seagal would later reprise his role in Under Siege 2: Dark Territory.
The following weapons were used in the film Under Siege:
William Stranix (Tommy Lee Jones) uses a Heckler & Koch P7M8 throughout the movie. He holds it high during many scenes, clearly showing the single stack 8 round magazine.
Several characters wield the Beretta 92F throughout the film, among them Commander Krill (Gary Busey) and Doumer (Colm Meaney). Ryback fires one as he fights off the terrorists while planting a bomb in the hull of the renegade sub.
Krill uses a silenced Ruger MkII to take out Captain Adams (Patrick O'Neal). When Krill is sitting at the desk in the Captain's quarters, the Ruger logo is visible on the grip.

Ryback takes a suppressed Heckler & Koch MP5K and carries it throughout the film. At the time of the making of the film, it was a common weapon in Steven Seagal movies, the MP5K (not the PDW) but adapted to take a suppressor.
Some of the "MP5"s are full auto conversions of the Heckler & Koch HK94 rifle. One of the terrorists uses a long barreled HK94 with a 'slip over' fake suppressor to fire.
A Marine guard holds an M4-style rifle when he's taken out by terrorists. Since the Marine makes a high fall, the weapon probably is a rubber stunt weapon.
During the initial assault many of the terrorists are using obviously rubber weapons. They are cast from the real deal and used in any scene where stunts occur. It is much safer to wave around and hit other actors with rubber guns than the real thing.
