While not as imposing as the Marauder tank, what it lacks in size it more than makes up for in versatility. El Diablo has the advantage of being a fast unit, able to outrun larger vehicles as well as keep pace with other recon vehicles. Being so small, the El Diablo is cheap to produce and can be used to overwhelm more expensive units en mass.
Additionally, the El Diablo has the innate ability to use the ability Marked for Death. Marked for Death will allow the El Diablo to fire a single high powered shot at the target. If the shot ends up killing the target, the El Diablo will gain a massive rate of fire bonus for a short duration. This ability allows El Diablo to finish off weak targets and then use the Rate of Fire bonus to lay down the pain on other nearby enemies.
In the late game, the El Diablo can be upgraded so that shots from its cannon do splash damage to enemies. Using this upgrade, the El Diablo can be mixed in with any force to provide extra damage to enemy forces as regardless of the target that the El Diablo is fighting it will be damaging all nearby enemy units.
