Sniper (スナイパー [sniper] in Japanese) is one of the rarely used jobs evolved from Ranger. It has something of Thief and Assassin about it, and through association with Ranger is connected with Archer too. The difference is that Snipers mostly use Assassin-type abilities, while still using mainly bows and crossbows.
There is one prominent Sniper character, Shara from Tactics Advance.
