Roughneck is a rapid-firing gunship. It has a decent armor, able to withstand most of T1 anti-air defenses. Their most common use is for defending your base or protecting your teammates within your air territory. They are not effective as striking units, due to their low speed. For this purpose - use bombers, or Hornets. It has heavier armor but weaker weapon than its CORTEX counterpart, the Wasp.
