Saurer 4K 4FA armored personnel carrier

The Saurer 4K 4FA is an Austrian tracked armored personnel carrier built for troop transport with light armor, a two-person crew, and seating for eight infantry. In the Boko Haram Insurgency it is documented as Nigerian Army equipment that appeared in Boko Haram possession and was later recovered in non-operational condition, making it relevant as captured protected mobility rather than as a newly supplied insurgent vehicle.

ATT Monitor reported Austrian-made Saurer 4K 4FA APCs among armored vehicles in Boko Haram possession that appeared to match Nigerian Army equipment; HumAngle later reported Nigerian troops recovered a non-operational ex-Army Saurer 4K 4FA in the northeast, so this entry treats the vehicle as captured or recovered insurgent materiel rather than confirmed combat employment.

Nigeria acquired the type before the Boko Haram Insurgency and Nigerian Army examples were photographed in 2015 counter-insurgency operations in Borno State, with later reporting also documenting ISWAP capture of a Nigerian Army 4K-7FA.
