Up to 150 soldiers from the 104th Infantry Battalion at Finner Camp will travel to Fort Dunree to compete in combat as they prepare to travel to South Lebanon in June.
As well as the troops, two army helicopters and up to fifteen army vehicles will take part in the manoeuvres.
Comdt. Barry O’Riordain said he wanted to warn people that the operations, which take place today (March 22) and tomorrow, are routine and they should not be scared.
“This will be a large exercise which will see a fleet of army vehicles travel across Donegal from Finner Camp in Bundoran to Fort Dunree in Inishowen.
“We want to inform people that this is taking place in case they are wondering or worried by what they see and hear,” he said.
As well as full combat exercises, the soldiers will be completing various other operations in farmlands which have been rented for the exercises.
“We do not anticipate that the combat training will be needed when we reach Lebanon but we need to be full prepared,” added Comdt O’Riordain.
