PstOhj 82 or AT-4 Spigot is a wireguided soviet second generation ATGM that is considered as somewhat obsolete nowadays. The missiles penetration and first hit knock-out capability of a modern main battle tank hit in the front is somewhat questionable, and it does not use the top-attack as modern anti-tank missiles. However if wisely used it may still be lethal, especially against the Soviet T-series of tanks that have a fairly weak armour protection, as has been found out in recent conflicts. The guidance system of the PstOhj 82 also ensures a big probability for a first round hit. The system breaks down in burdens that can be carried by the three men crew.
