One of the more effective Cybran tactics is the use of Deceiver networks to move a relatively large force within enemy radar range, draw off their mobile units with another, smaller group of units, then send in the stealthed units to do considerable damage to a base that is now, in theory, relatively lightly defended. The Fire Beetle is a "natural" choice for the stealth force, although considering its poor track record, this does not mean it should automatically be included in any attack you make utilizing stealth.
