Bandage CAN'T have animation because BF2 engine, you drop your bandage to use. Or just hold it and use it (Not in FH2, but vanilla).
We couldn't use 'just hold' because you'd never be able to give it away if you're yourself not at 100% health.
So dropping = no possible animation... Besides the throwing animation.
As for crawling, I wish for that too. At least, I wish guns would be held in a fashion that made it clear you are lying flat on the ground. Perhaps a greater amount of sway as you move foward and the sound effect might suffice. But its quite cosmetic...
PS. Can you rename your thread to something like 'Crawl & Bandage Use animation'?
Current title doesn't help people find it later.
