The Nigerian Army (NA) is the largest component of the Nigerian Armed Forces, and responsible for land warfare operations. It is governed by the Nigerian Army Council (NAC).
Given its considerable investment in materiel, the Nigerian Army has generally been perceived as one of the better equipped fighting forces on the African continent. It bears the brunt of the nation's security challenges, notably the Boko Haram insurgency.
The original elements of the Royal West African Frontier Force (RWAFF) in Nigeria were formed in 1900. During the Second World War, British-trained Nigerian troops saw action with the 1st (West Africa) Infantry Brigade, the 81st and the 82nd (West Africa) Divisions which fought in the East African Campaign (World War II) and in the Far East.
In Nigeria, from a force of 18,000 in infantry battalions and supporting units, strength rose to around 126,000 in three divisions by the end of the Nigerian Civil War in 1970. In terms of doctrine, the task of the Federal Nigerian army did not fundamentally change: its task remained to close with and defeat an organised enemy.
