US Navy officer gives briefing; map of region is shown. NOTE: Material on Master Tape #1342 covers preparations for and the carrying out of a retaliatory assault on an Iranian oil platform, and its subsequent destruction. The assault was made by US Marines on board the USS Trenton (LPD 14). Footage includes shots of damage done to the USS Samuel B. Roberts (FFG 58). Unfortunately, the actual assault is only covered by boring, black and white TAC (target acquisition camera) footage of the ocean.
