These details are contained in the weblink above, graciously translated for us by the Beegeagle’s Blogger, Oga Obix who is based in the CIS orbit and is fluent in Russian.
The article shows two photos of the BTR-3 which were taken from this blog, in Nigerian military service. Yes, Beegeagle’s Blog is monitored in Russia and Ukraine as well.
Moving on, the article puts the date of shipment at February 2013 (never mind the erroneous date shown on some photos which has to do with the camera’s settings).
So it is official. The Nigeria Police Force also now field BTR-3 APCs and they were acquired from The Ukraine. The Police Counter Terrorist Unit and the Police Mobile Force also use sturdy and rugged AutoKraz lorries manufactured in the east European country.
