While this ability is active, Pvt. Bullit's damage limit greatly decreases, and all defensive buildings near him will target him.
Each use costs 2 more Energy than the previous one, with a starting cost of 3 Energy.
Taunt is very useful to protect your troops from high-damage defenses. Not only will the defensive buildings' damage be redirected away from the troops, said damage will also be greatly reduced.
You can use the Taunt ability with Smokey Warriors; the ability can soak up damage from defenses behind the Warriors, which can save the need for Shock Bombs against those defenses.
Be very careful when using Taunt in the vicinity of area damage buildings. These defensive buildings' splash effects can hit other troops along with Bullit. This is especially important whenever using Smokey Warriors or Zookas with Bullit.
Taunt does not affect defenses that cannot attack Pvt. Bullit. Such defenses would target other troops normally if there are any within its range. For example, if Pvt. Bullit is out of range of a Flamethrower directly behind the Headquarters during a Smokey Warrior attack, the Flamethrower will attack Warriors normally if not shocked.
Keep in mind that long-range defenses like the Rocket Launcher, even if they can attack Pvt. Bullit, can be out of range of Bullit's taunt and so it will be unaffected by the taunt as a consequence, thus attacking troops normally. In these cases you cannot use Bullit to force these defenses to attack him unless you move him closer.
To defend against this ability, avoid placing many high damage single-target buildings (such as Cannons and/or Boom Cannons) together. If all high damage single target buildings are placed together, the ability can affect all of the buildings at once, rendering them much less effective.
