Here is a second video I made, partly for entertainment and partly to make the point that while some glitches are harmless, some are clearly cheating and should not be allowed. I do these glitches for entertainment purposes on an empty server. If management wants to delete this video so people don't use these on servers then I understand. I did not include some other ones, like getting inside the Hastings temple or the concrete supports on the big bridge or some involving jeeps as there weren't any on this server. I will provide some thoughts on each of these.

The first one is a pretty harmless and just for entertainment, it involves pushing a mortar into the sky as high as you want to go, even higher then I have it in the video. Once you fire it drops down and you die.
The second I would consider cheating as with any wall glitch. It involves using a vehicle to get under the steps on the main USA barracks at thier main base. It's just like any other wall glitch where the enemey can't see you or shoot you, but you can shoot them. It also is within flag range so you can take the main base flag.
The third is harmless and just looks funny. Run backwards on a ladder and the guy looks pretty crazy looking.
The last one is another I would consider cheating. It allows you to fit an almost unlimited amount of people in the back of a Mi8.
These people could be 10 teammates all with wrench's and they are able to repair in flight, which makes a Mi8 pretty much unstoppable. Or it could be used by a NVA soldier with 10 USA guys in the back allowing them to go around and take flags without the NVA being able to destroy it. You can do the same with a huey, although there isn't as much room as a mi8 making it harder to stay inside.
( Thanks to WolfDog for helping me record these. )
I would like to mention again I think the wall glitches and those simiar are clearly cheating, and should not be allowed on the HELLO server.
