Royal Marines conduct tactical insertion at night during 10-nation Exercise Tarassis

40 Commando's Royal Marines have conducted a tactical insertion at night using inflatable raiding craft during Exercise Tarassis in northern Norway.

Three raiding craft, full of marines decked out in night-vision goggles, can be seen crossing towards a beach in the pitch dark, before getting onto the beach, according to footage released by the Ministry of Defence.

The marines had to endure a two-hour transit through the Norwegian fjords with a wind chill reading of -10°C ahead of their night raid.

A tactical insertion involves marines quickly deploying into a possible hostile environment with an element of stealth for a specific mission.

Ex Tarassis sees the 10 nations of the Joint Expeditionary Force unite with Canadian forces for the most ambitious live operation since the coalition was formed in 2014.

It is bringing together thousands of troops, sailors, and aircrew, as well as dozens of ships and aircraft, in a large-scale exercise spanning the North Atlantic, Scandinavia, and the Baltic Sea region.

The aim is to allow member nations to practise working together, helping to refine their ability to respond to a crisis and strengthening their ability to operate as a unified force.

The training will run from early September to the end of October, comprising several exercises across land, sea, air, space and cyber, including Exercise Arctic Tide, an amphibious operation.

Ex Arctic Tide will demonstrate the UK and Norway's ability to deploy and resupply their forces anywhere in northern Europe.
