A sniper is a marksman or qualified specialistwho 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. Snipers typically have highly selective or specialized training and use crew-served high-precision/special application rifles and optics, and often have sophisticated communication assets to feed valuable combat information back to their units or military bases.

A bricklayer, which is related to but different from a mason, is a craftsman who lays bricksto construct brickwork. The terms also refer to personnel who use blocks to construct blockwork walls and other forms of masonry.[1]In British and Australian English, a bricklayer is colloquially known as a "brickie".[2] A stone mason is a term applied to one who lays any combination of stones, cinder blocks, and bricks in construction of building walls and other works. The main difference between a bricklayer and a true mason is skill level: bricklaying is a part of masonry and considered to be a "lower" form of masonry, whereas stonemasonry is a specialist occupation involved in the cutting and shaping of stones and stonework.
