When a sniper bitch comes around to your home base and starts picking off people that are waiting around for heli's and jets, you can slowly aim your howitzer for some pretty stress-relieving explosions.
I, personally, try to see how high and how far I can make the body fly. I knocked about 4 guys completely across my base last night.
Another fun thing to do is hit circling heli's with a howitzer.... they go 'booom!'.... only bad part is when the rubble falls on a group of guys waiting for heli's and jets...
Honestly, waiting for a helis and jets isn't a good idea, folks (and most idiots jump into the helis and have no idea how to fly them... if you don't know how to fly them (raises hand), then jump in and take a gunner spot! There is nothing more embarassing than a full heli (8 or so guys) lift off and crash before they reach the end of the base)
Anyone else big into desert combat? I usually play on BIG servers that are full of people (like 32-40 max players, almost full, punkbuster enabled, with low ping). If so, I go, surprisingly, by 'fortknox', so come lookin for me... I play after 8pm (EST) on weeknights until about 10.
