Sniper

sniper

A sniper is a highly trained marksman who operates alone, in a pair, or with a sniper team to maintain close visual contact with the enemy and engage targets from concealed positions or distances exceeding the detection capabilities of enemy personnel. These sniper teams operate independently, with little combat asset support from their parent units. Snipers typically have highly selective and specialized training and use high-precision/special application rifles and optics, and often have sophisticated communication assets to feed valuable combat information back to their units.

In addition to marksmanship and long range shooting, military snipers are trained in camouflage, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition.

With the exceptionof the Pertharians and the old Saresii (First Age of Knowledge ) no other known civilization has developed the concept of snipers. And none has it developed with in such a degree as the Terrans (and in extend the Union miliary)

Union Marines are the unquestioned leaders  in this type of war craft.
