Malaysian has requested to modernize its fleet of ACV-300 a tracked AIFV (Armored Infantry Fighting Vehicle) which is used as APC (Armored Personnel Carrier) and IFV (Infantry Fighting Vehicle) in the Malaysian Army. It is a development of the ACV-15 developed by the Turkish defense company FNSS Savunma Sistemleri. The Malaysian Army variant of the AIFV is called the ACV-300 Adnan and is a result of a collaboration between FNSS and 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.
FNSS developed the ACV-15 to meet the Turkish Land Forces Command’s (TLFC’s) operational requirement. The first production vehicles were delivered in 1992. FNSS Defense Systems’ latest development is the Armored Combat Vehicle New Generation which has an additional roadwheel on 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 Adnan features a 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. The 10 variants are: Infantry fighting vehicle with one-person Sharpshooter turret armed with ATK Gun Systems Company 25 mm M242 Chain Gun and 7.62 mm coaxial machine gun, Anti-tank with Pakistani Baktar Shikan ATGW system, Armoured personnel carrier, Command post vehicle, Mortar carrier, Recovery vehicle, Fitters vehicle, Signals vehicle and Cargo carrier
