FNSS developed the ACV-15 based on the AIFV to meet the Turkish Land Forces Command's (TLFC's) operational requirement. The first production vehicles were delivered in 1992. The basic AIFV has a one-person power-operated turret armed with a 25mm cannon and 7.62mm co-axial machine gun. FNSS Defense Systems' latest development is the Armored Combat Vehicle - New Generation which has an additional roadwheel each side. This can undertake a wider range of battlefield missions as it has greater internal volume and load-carrying capability. The vehicle is fully amphibious, propelled in the water by its tracks. Standard equipment includes passive night vision equipment, an NBC (nuclear, biological, chemical) protection system and smoke grenade launchers.
The AIFV is in service with Turkey (2249) and the United Arab Emirates (136 delivered). Malaysia ordered 211 ACV-15 in different versions in 2000, all of which have been delivered.
The Malaysian variant of the AIFV is called the ACV-300 Adnan and is a result of a collaboration between FNSS and the Malaysian company DRB-Hicom Defence Technologies (Deftech). They are nicknamed the Adnan after Adnan bin Saidi, a Malayan Lieutenant hero who fought in the Battle of Singapore during World War II. The ACV-300s are equipped with a 25mm Sharpshooter Turret and are assembled by Deftech at Pekan, Pahang. 12 units were deployed against Sulu terrorists in the 2013 Lahad Datu standoff.
The ACV-15 can be fitted with a number of turret choices to tailor to individual customer requirements. They are also equipped with firing ports, which allows infantrymen to fire their weapons from within the vehicle.
The ACV-15 has also been fitted with the turret of a BMP-3 infantry combat vehicle, produced by Instrument Design Bureau (KBP) of Tula, Russia. The system is called ACV-SW. The BMP-3 turret is armed with a 100mm 2A70 semi-automatic rifled gun/missile launcher, which can fire either HE-FRAG (High Explosive-Fragmentation) rounds or the 9M117 laser beamriding anti-tank missile.
The Adnans feature KVH TacNav navigation system incorporating GPS, LWD Avimo laser warning device, Wegmann type 76mm grenade launchers, NBC filtration system and ANVVS-2 night vision system.
