What it looks like when Marines fire their biggest guns

Right now, the Australian Army is hosting one of its largest military exercises with participants from the U.S. Marine Corps and the French military working side-by-side with Australian forces. The three militaries are practicing how to work with each other as well as how to best incorporate the strengths of each force.

And that gives us a perfect chance to watch the highly mobile, flexible, and lethal Marine artilleryman at work.
