Above you can see a High Explosive artillery 155 mm round being fired from an M109A6 Paladin, in a live-fire training at Combined Resolve IX at Grafenwoehr Training Area, Germany.

That is the subject of this Photo Of The Day.

The updated A6 Paladin version can come from the move to a halt and fire accurately within 30 seconds, a process that took several minutes with earlier versions.  (Source)

The Paladin can store up to 39 pcs of 155 mm rounds.
