London, United Kingdom—The British government has announced an additional deployment of troops in Ukraine and a package of financial support.

The British Defense Secretary Gavin Williamson said that an extra contingent of Royal Marines would deploy to the eastern European country as an extra layer of deterrence against Russia.

The Royal Marines are Britain’s premier amphibious and light infantry unit. They will be providing combat and naval training to the Ukrainian military as part of Operation Orbital. The training and advising mission began in 2015. Hitherto, British servicemen have trained close to 10,000 Ukrainian soldiers. Training has been focused on medical, infantry, anti-tank, anti-artillery, and anti-sniper skills. British troops have also provided Improvised Explosive Device (IED) detection and logistics support to their Ukrainian counterparts.

The UK isn’t the only country supporting Ukraine in her struggle against the Russian-supported separatists. The U.S., Canada, and several European countries have committed to training and logistical support.
