Unbeknownst to us, the Tanzanian Special Forces adopted the IWI Galil MAR compact carbine along with Meprolight Sights and Bulgarian night vision googles. The troops in these photos are taking part in a multinational training exercise as part of the United Nations Intervention Brigade in the Democratic Republic of the Congo.
The rifle and sight are impressive equipment for a country that has a mean wage of just $0.52/hour. The cost of each rifle and sight is probably equivalent to three years of its operators wages. This would be like supplying a rifle and scope that costs $60,000 to a US Army Private First Class (E3). Judging from photos, not many of them are issued night vision googles.
UPDATE: We originally identified the rifle as the Galil ACE, not the Galil MAR.
