Master Corporal Presley was deployed with C Company, 1 PPCLI Battle Group during Operation ARCHER. On July 15, 2006, while conducting operations in Sangin District, Afghanistan, dismounted elements of Master Corporal Presley’s company were the target of an intense and sustained ambush by a significantly greater enemy force. With a portion of his company cut off, he maintained his exposed position on his light armoured vehicle, at great personal risk, to control the fire of the main cannon while simultaneously engaging the enemy with the mounted machine gun. Master Corporal Presley’s fortitude and selfless actions were instrumental in repelling the enemy and permitted his company to break contact with the enemy.
