Steyr 4K 7FA armored personnel carrier

The Steyr 4K 7FA G 127 is an Austrian tracked armored personnel carrier developed from the Saurer 4K 4FA line with extra armor, a more powerful 320 hp diesel engine, and automotive components related to the SK 105 light tank. 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.
