MARCOS (Marine Commandos, formally the Marine Commando Force) is the special operations unit of the Indian Navy, raised in 1987 and trained to fight at sea, from the air and on land. It is one of several Indian special forces, alongside the Army’s Para (Special Forces), the Air Force’s Garud Commando Force and the Home Ministry’s NSG. This page covers MARCOS in detail and then compares India’s main special forces, a frequent GS Paper III and Prelims topic.
Quick Answer
MARCOS: Indian Navy special forces, raised in February 1987 as the Indian Marine Special Force and renamed Marine Commando Force in 1991. Nicknamed "Magarmach" (crocodiles). Roles: maritime counter-terrorism, hostage rescue, raids and amphibious operations. Known for operations in Sri Lanka (1987) and the 26/11 Mumbai attack (2008). Other special forces: Para SF (Army, 1966), Garud (IAF, 2004), NSG (MHA, 1984), SFF (1962). The Armed Forces Special Operations Division (AFSOD), set up in 2019, brings the three services’ special forces under one tri-service command.
MARCOS: Origin and Role
The Indian Navy raised the Indian Marine Special Force (IMSF) in February 1987, with its first officers trained alongside the US Navy SEALs and British Special Boat Service. It was renamed the Marine Commando Force in 1991, giving the abbreviation MARCOS.
Roles
- Maritime counter-terrorism, including recapturing hijacked ships and offshore oil platforms.
- Hostage rescue at sea and in coastal areas.
- Special reconnaissance and direct-action raids behind enemy lines.
- Amphibious operations in support of larger forces.
- Counter-insurgency: a MARCOS unit has been deployed in Jammu and Kashmir, around Wular Lake, since 1995.
Training and selection
Selection is open to volunteers from the Navy. Training runs for roughly two and a half to three years, including parachuting (at Agra), diving (at Kochi), combat swimming, close-quarter battle and counter-terrorism. Attrition is very high; most volunteers drop out in the pre-selection phase. MARCOS are HALO/HAHO-qualified and can deploy from submarines.
Notable operations
- Operation Pawan (1987): as part of the Indian Peace Keeping Force in Sri Lanka, MARCOS swam into Jaffna and Trincomalee harbours to attack LTTE boats.
- Operation Cactus (1988): in support of the operation that reversed a coup attempt in the Maldives.
- Operation Black Tornado (2008): joined the counter-terror operation at the Taj Mahal Palace hotel during the 26/11 Mumbai attacks.
- Anti-piracy missions in the Gulf of Aden and the Arabian Sea, including the rescue of the bulk carrier MV Lila Norfolk in January 2024.
India’s Special Forces Compared
| Force | Service / Ministry | Raised | Main roles |
|---|---|---|---|
| Para (Special Forces) | Army | 1966 (9 Para SF) | Deep strikes, cross-border raids, counter-terrorism |
| MARCOS | Navy | 1987 | Maritime special operations, hostage rescue at sea |
| Garud Commando Force | Air Force | 2004 | Airbase protection, combat search and rescue, airborne operations |
| National Security Guard (NSG), "Black Cats" | Ministry of Home Affairs | 1984 | Counter-terrorism, anti-hijacking, VIP security |
| Special Frontier Force (SFF) | Cabinet Secretariat (under RAW) | 1962 | Covert operations, high-altitude warfare |
| CoBRA | CRPF (Ministry of Home Affairs) | 2008 | Jungle warfare against Left Wing Extremism |
State police forces also have elite counter-terror units, such as the Greyhounds (Andhra Pradesh and Telangana) and Force One (Maharashtra).
Armed Forces Special Operations Division (AFSOD)
Set up in 2019, the AFSOD is a tri-service division under the Integrated Defence Staff that draws on Para SF, MARCOS and Garud for joint missions. Its creation followed the recommendations of the Naresh Chandra Task Force (2012) to integrate the special forces, along with the Defence Space Agency and the Defence Cyber Agency.
Issues for Mains
- Jointness: each service trains and equips its own special forces; AFSOD is a step towards integration but is still small.
- Equipment: specialised boats, submarines for swimmer delivery, night-vision and communication systems remain uneven.
- Use in counter-insurgency: deploying elite units for routine counter-insurgency can blunt their core strategic role.
- Legal framework: cross-border operations raise questions under international law, as debated after the 2016 surgical strikes.
