Noteworthy operations conducted by MARCOS include Operation Zabardust, Operation Tasha, Operation Pawan, Operation Cactus, Operation Black Tornado, and many more.

APS (Avatomat Podvodny Spetsialny) – Assault Rifle

The APS (Avatomat Podvodny Spetsialny) is an underwater assault rifle originally designed and developed by the Soviet Union in 1975 to counter the threats posed by underwater enemies. During the Cold War between the USSR and the United States in the 1970s, the rising threat of attacks from frogmen in the USSR naval bases necessitated the development of an effective underwater weapon. 

The AK-47, one of the most lethal weapons, was unsuitable for underwater use. To overcome this challenge, the APS underwater assault rifle was introduced, becoming a major weapon for the Soviet frogmen.
