Resurrected!

I thought Soldier rocket jumping was pretty weak, until I saw it done properly:

Dude says to crouch->jump->fire for much better heights. He's able to rocket jump from the ground to the C cap on Granary. That's pretty high.

If Soldier rocket jumping is decent, demo gren jumping is totally off the hook.

At one point on 2Forts he gren jumps across the moat and onto the opposing deck with one jump. Craziness!

Finally, here's a great resource for some script snippets.

Also, please look around that site. I've already updated some Engineer info, and written this section on 2forts:
