Notes: The AIFV originally developed as a private venture by FMC as a possible replacement for the M-113 in the US Army. FMC went on to develop what became the Bradley, but the AIFV was, in the meantime, sold to some of the US’s NATO partners, especially to Belgium and the Netherlands, who bought them in large numbers, and eventually obtained a license to build them in their countries. More were bought by the Philippines and Pakistan (who also license produced them) and Egypt. The AIFV was also developed into the Turkish TIFV series. There are 23 variants of the basic vehicle.

The basic AIFV IFV is basically an M-113 chassis with appliqué armor added to the HF and HR, a turret mounting a light autocannon mounted on top, two firing ports on each side and one in the rear, a searchlight, and a better suspension for a smoother ride.

The AIFV CPV is the command post carrier variant of the AIFV, used by Belgium and the Netherlands. It is basically an AIFV with the turret removed, and unlike most command post carriers, without the roofline raised. There is a commander's position with an M-113-style cupola, mounting an M-2HB. Inside, there are at least 3 radios, a mapboard, a field computer, various drawers with office supplies, and a folding table and chairs to set up outside under the tent that may be erected at the rear.

Notes: This is an international development by Austria and Spain. It is in service with Austria (where it is known as the Ulan), Greece (where it is known as the Alexandros), and Spain (where it is known as the Pizarro). Though specialized versions (such as ATGM, mortar carrier, ambulance, engineer, recovery vehicle, and others) were planned, very few of these have actually been built yet. The ASCOD is designed to be easily serviced, with the engine, transmission, and cooling system changeable in about 30 minutes. The commander and gunner have hatches on the turret roof, the driver on the front deck, and passengers have hatches on the rear and passenger compartment deck.

Notes: This vehicle was conceived by Czechoslovakia and Poland as an upgraded version of the BTR-50PK, entering service in 1964 with Czechoslovakia and 1966 with Poland. The improvements over the BTR-50 include an NBC system, higher speeds, a fully enclosed weapon station, and doors in the sides of the passenger compartment. There are at least 8 variants, including several APCs with different armament, a recovery vehicle, an ambulance, and several command versions. They are still in service with the Czechs and Polish, as well as Bulgaria, Iraq, India, and several African nations. In addition, Israel captured almost 100 of them during several past wars and equipped some of their reserve units with OT-62s. The T-21 is a Czech/Polish version of the Russian B-10 recoilless rifle.
