In 1991, the Hellenic Army inquired with the recently unified Germany about purchasing most of the military equipment of the former East Germany. As the Bundeswehr found no use for Eastern Bloc vehicles, the deal was signed that year, resulting in large batches of vehicles being delivered from 1992 to 1994. Among these were the Osa-AKM (9K33M2) SPAA systems. As of 2024, 38 Osa-AKMs remained in service with the Hellenic Army, with some being sold to Armenia that year.

The Greek Osa-AKM was introduced in Update 2.59 "Sky Odyssey" as part of the Israeli tech tree. It is functionally identical to its Soviet counterpart. The Osa-AKM can reliably engage manoeuvring aerial targets at ranges of up to 10 km and is capable of guiding two missiles onto a single target simultaneously. Thanks to its wheeled chassis, the Osa-AKM enjoys excellent mobility, allowing it to take up unexpected positions against enemy aircraft. However, the vehicle has a large silhouette, no meaningful armour protection, and its missiles are mounted at an upward angle, leaving it virtually incapable of engaging ground targets.
