For the purpose of the GFP ranking, the "armored fighting vehicle" (AFV) is represented by Armored Personnel Carriers (APCs) and Infantry Fighting Vehicles (IFVs). Examples include the American Bradley Infantry Fighting Vehicle and the Soviet/Russian MT-LB series. While generally tracked in nature, AFVs can also showcase road wheels along multiple axles as in the American Stryker. Systems on order heading into the new year are NOT taken into account.
