The Nigerian Army is being re-equipped in an effort to combat Boko Haram insurgents and has been bolstered by armour from the Czech Republic, which is delivering four BMP-1 infantry fighting vehicles to Nigeria this year, together with six RM-70 122 mm self-propelled multiple rocket launchers and at least four T-72M1 tanks. These are all second hand vehicles ordered in 2014. The tanks were first seen being flown to Nigeria in January this year.
