Dust Tactics: Heavy Ranger Tank Hunter Squad – "Tank Busters" 2011

Game description from the publisher:

Add the speed and power of the "Tank Busters" to your Dust Tactics forces! These new Allied soldiers seem to be a contradiction; despite their heavy combat armor they are able to move across the battlefield at lightning fast speed. The Tank Busters' specialty is to function as highly effective anti-armor units.

Each member is equipped with a reactor-fueled bazooka that can waste enemy armored vehicles. Take advantage of their phenomenal speed to reach an enemy walker no matter where it hides; they are able to ignore obstacles in their path by flying over them! Should their bazookas fail them, these unbelievably strong individuals can punch through a walker's armor during close combat.
