The Grizzly APC is a 22-ton infantry mobility vehicle designed and manufactured by Academi for urban combat. ==Design== 4x2, 4x4, and 6x6 versions with three different Caterpillar diesel engines are available. Its armor, called the "Blackwater High Threat Armor Protection System" is claimed to defeat .50 caliber rounds as well as IEDs. It is constructed of AR500 steel, and incorporates angled walls and a v-hull chassis to deflect the blast waves produced by explosives. It uses Fiber-Tek armor reinforced belly and lowers, with a fully enclosed drive train.〔(Blackwater USA )〕 ArmorThane tactical coating on the interior and exterior reduces spall probability. There are two top-side egress hatches, five gun ports (two on each side and one in rear), and transparent armored windows, capable of NIJ level 3 protection. The Grizzly makes use of forward and rear 400,000+ candle power halogen searchlights, which can be operated remotely. It also has a ringmount roof turret, capable of mounting a 12.7mm machine gun, which may be operated from a remote weapon station. Blackwater USA submitted two Grizzly APC vehicles to the U.S. military, with EXO Scale anti-EFP appliqué armor from ARES Systems Group, for the MRAP II competition at the Aberdeen Proving Ground.〔(http://www.ares-sg.com/teamroom/readingroom.asp )〕 According to the Army Times, the armor passed the testing, but the vehicle failed due to limited armor on the forward area of the vehicle (pictures on ARES' website shows less armor was used over the frontal area of the cab.) Blackwater had been hoping to discuss adding more armor to the forward area and threatened an automatic protest but it was disregarded, according to an Army Times source.〔(DoD won’t buy MRAP II, sources say - Army News, opinions, editorials, news from Iraq, photos, reports - Army Times )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grizzly APC」の詳細全文を読む スポンサード リンク
