ブレン軽機関銃
FV432s in service with infantry battalions are equipped with a pintle-mounted L7 GPMG (if not fitted with the Peak Engineering turret). Vehicles with the Royal Artillery, Royal Engineers and Royal Signals were originally fitted with the L4A4 variant of the Bren light machine gun, but they now use the GPMG. When equipped with the GPMG, the vehicle carries 1,600 rounds of belted 7.62mm ammunition; when carrying the Bren LMG, the vehicle carried 1,400 rounds of 7.62mm ammunition (50 magazines, each holding 28 rounds). There are two three-barrel smoke dischargers at the front.
