Cold War (TV story)

 was the eighth regular episode of the seventh series of Doctor Who produced by BBC Wales. It saw the first televised appearance of the Ice Warriors since The Monster of Peladon 39 years previously, and their first appearance in the BBC Wales version of the show.

Synopsis
On a Soviet submarine in 1983, a frozen alien warrior is waking up, just as the TARDIS materialises. According to the scientist on board he has been frozen for 5000 years. When he escapes, he is revealed to be the "heroic" Grand Marshall Skaldak. Initially, peace may have been made, until one of the crew members instinctively attacked Skaldak and convinced him he was at war with the human race under Martian law. He therefore attempted to use the submarine's nuclear missiles to destroy the planet, but was eventually persuaded by the Doctor that destroying the planet wasn't worth anything to him. Skaldak's allies' craft pulled the submarine up and over the ice before summoning their Grand Marshall and leaving the planet, deactivating the warheads.

 * This is the first time an Ice Warrior is (partially) seen not wearing armour.
