The recruits practice their war skills with capture the flag games. Each participant carries visible-laser weapons (color coded to match the team color) to fire at members of the other team, and wears a special vest that detects when it is hit with a laser, flashing briefly with red lights on the front and back and thereafter delivering a debilitating shock to the wearer until the game is over.
All telecommunications in the film are based on either a public address or a two-way radio metaphor.
To address the crew from inside the ship, Commander Adams grabs the microphone from its holder on the wall. Its long handle makes it easy to grab. By speaking into the lit, transparent circle mounted to one end, his voice is automatically broadcast across the ship.
The two-way radio on his belt is routed through the communications officer back at the ship. To use it, he unclips the small cylindrical microphone from its clip, flips a small switch at the base of the box, and pulls the microphone on its tether close to his mouth to speak. When the device is active, a small array of lights on the box illuminates.
The microphone also has a video camera within it. When Chief Quinn asks Commander Adams to activate the viewer, he does so by turning the device such that its small end faces outwards, at which time it acts as a camera, sending a video signal back to the ship, to be viewed on the view plate.
The Viewplate is a large video screen with rounded edges that is mounted to a wall off the bridge. To the left of it three analog gauges are arranged in a column, above two lights and a stack of sliders. These are not used during the film.
The Viewplate is controlled by a wall mounted panel with a very curious placement. When Commander Adams rushes to adjust it, he steps to the panel and adjusts a few horizontal sliders, while craning around a cowling station to see if his tweaks are having the desired effect. When he’s fairly sure it’s correct, he has to step away from the panel to get a better view and make sure. There is no excuse for this poor placement.
