This is my best creation yet, my 120 mm howitzer. Actually, it's a 1,200 mm howitzer, but just pretend it's 10 times smaller.

Anyway, there's an enemy bunker on the other side of these hills, about 550m away. Let's get 'em.

How to use this howitzer:
1. Make sure the breech is open completely. Open it by pulling down on the grey lever.
2. Slide the shell into the breech. Push it all the way in so the breech block moves up slightly and the shell is held in place. make sure the breech block's locking pin is not in the way of the block.
3. Close the breech by pulling the grey lever all the way up.
4. Lock it shut by pushing the gold lever forward.
5. Aim with the white handle on the gear located beneath the barrel.
6. Once it's aimed, pull on the lanyard to fire. The throw on the trigger mechanism is relatively long.
7. Unlock the breech by pulling the gold lever back and open it by pulling the silver lever all the way down, until the shell casing is ejected.
8. Repeat from step one.

The shells have safety mechanisms to prevent unintentional detonation. The mechanism will be destroyed when the shell is fired.

Enjoy!
