Defence College of Technical Training Schools - The Defence School of Marine Engineering at HMS SULTAN, one of the six recently formed Defence College of Technical Training Schools, is currently delivering a ten (10) month joint Army/Navy Marine Engineers career course for a combined class of Army Corporals and Navy Leading Hands.    For the Army, the joint training model, in addition to financial savings, will open the possibility of embedding soldiers with the Royal Marine Amphibious Assault Squadrons who currently rely on the Navy for engineering support.     It also arms the individual with an NVQ Level 3 in Engineering Maintenance which is achieved once they complete mandatory engineering tasks in their sea training journal.
