On June 2 a new rotation of the Portuguese Armed Forces deployed in Lithuania. The Portuguese Marine Corps unit of approx. 150 troops deploys as part of the deterrence measures agreed by NATO to counter the threats facing the Alliance. The Portuguese military will be training with the Lithuanian Great Hetman Jonas Karolis Chodkevičius Infantry Brigade Griffin, Special Operations Forces and the Navy until the end of August. They will be based at the Brigadier General Povilas Plechavičius Training Area in Kairiai.
Portugal has been sending rotational forces to Lithuania since 2015 as part of the NATO Assurance Measures (air, maritime and land measures in the Central European and Eastern European NATO Allies) in a staunch demonstration of solidarity by contribution to deterrence and defence in the eastern flank of NATO. Portugal has been actively supporting the NATO Assurance Measures in Lithuania with rotation of Portuguese Marines and contributions to the NATO Air Policing Mission in the Baltic states.
