Stillbrew armour

Stillbrew armour, or more correctly, the Stillbrew Crew Protection Package (SCPP) was an add-on passive composite armour applied to the FV4201 Chieftain main battle tank used by the British Army's Royal Armoured Corps in the mid-1980s and early-1990s so as to provide increased protection from anti-tank warfare weapons. It was named after the two men that invented it, Colonel Still and John Brewer, from the Military Vehicles and Engineering Establishment in Surrey. The tanks to which it was fitted were colloquially referred to as Stillbrew Chieftains.
