Watch Marines bring out the big guns at one of Europe’s largest war games

Every Marine is a rifleman — we all know this to be true. One Marine and his rifle can deliver a world of hurt unto the bad guys. But it's been a long time since Marines have relied on rifles alone to complete the mission.

In fact, Marines often employ guns that are a heck of a lot bigger than an M16 rifle, like the M777 howitzer. The M16 fires a 5.56mm round. The M777 fires 155mm rounds — nearly 28 times larger. If a Marine delivers a world of hurt with a rifle, then they deliver an entire galaxy of pain with a howitzer.

But, just as with rifles, learning how to use a howitzer requires practice — the sort of practice best done at large-scale war games.

Believe it or not, it's a lot more complicated than just pointing the howitzer at the enemy, loading it, and pulling the lanyard. The M777 weighs over 8,250 pounds and fires shells at targets up to 19 miles away with a normal HE round (other rounds have a longer range). This gun is operated by a crew of seven, each of whom play an essential role in sending rounds (very far) down range.

This howitzer has been used by American troops since 2005 and has seen plenty of action in Iraq and Afghanistan, where both soldiers and Marines have used this big gun to take out al-Qaeda, ISIS, and the Taliban. This British design has also been acquired by Australia, India, Saudi Arabia, and Canada. Funnily enough, British troops don't use this big gun.

One motivated Marine with his rifle is bad news for the enemy — now imagine what seven motivated Marines can do with a howitzer!
