Clyde-based Royal Marines from 43 Commando Fleet Protection Group recently took part in a security exercise with the Indian Navy.
Exercise Konkan is an annual military training operation involving the Royal Navy and Indian Navy.
This year, the week-long exercise involved joint boarding as well as battle and casualty evacuation training.
43 Commando regularly provide Royal Marine Boarding and Maritime Sniper Teams to navy ships deployed on counter-piracy, counter-narcotics operations around the world.
Recently, a Royal Marine sniper from 43 Commando, operating from Royal Fleet Auxiliary (RFA) ship Wave Knight, assisted in the seizure of more than £40m worth of cocaine in the Caribbean.
Colonel Jock Fraser MBE, commanding officer of 43 Commando, said: “I am delighted that Royal Marines from 43 Commando have been able to carry out this joint exercise with the Indian Navy.
“The exercise has given us an opportunity to learn a lot from each other regarding the tactics and procedures necessary to effectively conduct specialist maritime boarding operations anywhere in the world.
“I would like to thank the Indian Navy for the very warm welcome we have received.”
