Terminology

• Boomerang (Fleetlock) - Calculating the time a fleet should return from a mission, and launching an attack that coincides with that fleets return.

• Fleet / Resource Saving (FRS) - The act of sending your ships and resources on missions for set periods of time in order to protect them from attack while you are not actively playing the game.

• Ninja Defend - A "Ninja Defense" is when someone sends an attack fleet thinking they have the superior force to take out their target, but when they arrive they find that their fleet is obliterated because the defender managed to get a support fleet in before theirs arrived. The timing is critical because the attacker can send a probe when they are just a few minutes out to confirm nothing has changed and if they see a massive fleet they will recall. Of course the defender's Ninja fleet arriving even a second after the attack fleet does the defender absolutely no good.

• Ninja FRS - The act of removing ones fleet and resources mere moments before an attacking force arrives, thus doing so in stealth leaving the attacker with no gains or glory.

• Oracle Lock - When someone who has an Oracle has your fleets locked in with an attack timed to land mere seconds after your fleets land at your planet. Or if it is a truly long deploy or attack they have oracled, they can lock it in with a harvester and join it later with the full fleet.
