Mass Effect & Mass Effect 2
Although they lack the brutality of the krogan, the skill of the asari, and the virtuosity of the humans, the turian military has formidable discipline. Enlisted personnel are thoroughly trained and stay calm under fire. Turian units don't break. Even if their entire line collapses, they fall back in order, setting ambushes as they go. A popular saying holds: 'You will only see a turian's back once he'd dead.'
Boot camp begins on the 15th birthday. Soldiers receive a year of training before being assigned to a field unit; officers train for even longer. Most serve until the age of 30, at which point they become part of the Reserves. Even if they suffer injuries preventing front-line service, most do support work behind the lines.
Biotics are uncommon. While admired for their exacting skills, biotics' motives are not always fully trusted by the common soldier. The turians prefer to assign their biotics to specialist teams called Cabals.
Command and control is decentralized and flexible. Individual squads can call for artillery and air support. They make extensive use of combat drones for light duties, and practice combined arms: infantry operates with armor, supported by overheard gunships. Strategically, they are methodical and patient, and dislike risky operations.
Tradition is important. Each legion has a full-time staff of historians who chronicle its battle honors in detail. The oldest have records dating back to the turian Iron Age. If a legion is destroyed in battle, it is reconstituted rather than replaced.
The turians recruit auxiliary units from conquered or absorbed minor races. Auxiliaries are generally light infantry or armored cavalry units that screen and support the main turian formations. At the conclusion of their service in the Auxiliaries, recruits are granted turian citizenship.
