Total Survival Suit
The Total Survival Suit (TSS) was a mobile combat and protective armour used by human colonial expeditions. It had directed beam weapons and was controlled by a direct link with the operator's brain. It was also capable of functioning autonomously with a simple program (such as "return to base"). The expedition to Deva Loka was outfitted with one Total Survival Suit.
Sanders used the suit when he left the expedition's dome to explore the area. Later, Adric used it to defend against Aris' attack. He was unable to control it effectively and his fear made its weaponry activate. The suit fired upon the Kinda and they fled. (TV: Kinda)
Adric was told off by the Fifth Doctor shortly afterwards for being so reckless with the TSS, as the entire Kinda tribe could have been wiped out as a result. (The Visitation)
