Bouncing units into the air?

[Grayswandir]

That's the thing...they won't always be dead when they go flying into the air (probably half-dead...but...), so the person who you just launched may be shooting at you still...
Also, on a related note, it's possible to use Propel/Repel to add in "recoil" correct? In Marathon (which I'm making the conversion for...), most of the weapons had a slight recoil when you fired, pushing you back.
And, on a completely different subject but since I possibly have your attention...is it possible to make a unit attack while moving (aka: run and gun...)?
