"We're just getting warmed up!"
The Legionnaire Tribe is a CPU controlled Wild Monster Tribe.Like other Wild Monster Tribes, they cannot gain Damage Protection and once their yard is destroyed, they will rebuild it and make it stronger. It is known for using a lot of Sniper and Cannon Towers and doesn't contain a lot of resources. In later levels they will be found with higher level Storage Silos and Harvesters, but without a proper strategy to farm, you wouldn't get too much. Usually a well-concentrated attack of Ichis, Fangs, and Crabatrons are enough to defeat them at a moderate level. At a lower level, Pokeys (preferrably Banditos) and a Drull are enough. At a higher level, it's best to use Zafreetis, Teratorns, Fomor (Level 3+) or Drull (preferrably level 4+) and Crabatron. From Level 28, once you destroy 3 Sniper Towers from your top left, you may fling Finks to destroy those General Buildings while other monsters are destroying other buildings. This may help speed up the destruction. Do this only once you destroy all Towers. They attack mostly with Project X and D.A.V.E.: up to 19 Project X and 38 D.A.V.E.s once you are in a higher level at your main yard, or if your outposts are strong enough by the system.
Legionnaire is weak on defending but stronger in attacking. Prepare your defenses should they attack.
Roughly what you can expect from a full destruction of a Legionnaire tribe:
In map room 3 a beginner can defet a level 20(somtimes 25) outpost if you put all yore monsters (50% tanks) near the sniper garding the twig area.(please correct spelling.)
