Jackhammer is a front-line Supertrooper whose very fast reflexes enable him to live up to his name. Jackhammer was once clocked at two hundred blows per minute in testing. With the strength he can bring to bear, this level of impact can generate sympathetic vibrations in structures sufficient to collapse buildings and damage the foundations of bridges, etc.

Jackhammer has also got one of the most active healing agents of any supertrooper, which is almost as effective as the Bio-Defence, but simply enables Jackhammer to get up again after any attack.
