M109A6 Paladin Self-Propelled Howitzer

The M109A6 Paladin Self-Propelled Howitzers are highly mobile combat support weapons. The Paladin allows firing in a 360 degree circle through its primary armament, the 155mm cannon assembly. The system is capable of both direct (line of sight) and indirect (out of the line of sight) firing. It can stop and fire the first round in under 60 seconds, allowing the vehicle to avoid counter-battery fire and gives shoot-and-scoot capability.
