The ROCA purchased 39 OH-58D Kiowa Warriors, known as the OH-58D戰搜直升機 (lit: combat reconnaissance helicopter), from the US in 1992 (26 purchased alongside a fleet of AH-1Ws) and 1999 (13 helicopters assembled by AIDC), and deployed them in the only two helicopter companies in the ROCA and Army Aviation Training Command. Although two helicopters have crashed during their service since 1992 (in 2001 and 2020), the ROCA will likely continue to operate the OH-58D for a number of years, thanks to up to 12 years worth of spare parts bought from the US.

Introduced in Update "Sons of Attila", the ROCA OH-58D performs identically with its American counterpart, only lacking the option to equip the 30 mm grenade launcher or 7.62 mm Minigun. It has small dimensions, AIM-92 Stinger missiles, and countermeasure pods, aiding its survival in combat and somewhat mitigating the lack of armour. It also has a mast-mounted camera, allowing it to make good use of terrain or treetops to conceal itself, while the four AGM-114K Hellfire II missiles will make light work of any enemy ground vehicle.
