The Lesotho Defence Force (LDF) is established under article 146 of the national Constitution, and charged with the maintenance of internal security and the defence of Lesotho. Its chief officer is designated "Commander" by the Constitution, and usually holds the rank of lieutenant-general. The LDF has a total strength of just over 3,000. The largest component is infantry, but they are supported by small artillery, logistics, and air force units, and a single armoured reconnaissance company. Since 2000, Lesotho Defence Forces have been trained by a small contingent of Indian Army Training Team, led by a Brigadier.
