Vigilant
From ARRSEpedia
First generation wire-guided (TOW) and steam-operated anti-tank missile. British built (like most things in the swinging '60s), the Vigilant was launched from a box-like container, whilst the operator targeted through a semi-remote optic - or something like that anyway. It was all very Heath Robinson, but hey... it was forty bloody years ago! It looked well dudey on the Ferret.
