they should be able to get up and move while crouched etc... like we would do.
i find this very important to get fixed as all AI battles are now "come on..."
*latest beta 26-7-13*
[EDIT] i have attached a simple example test mission, please extract and save to your (my documents, arma3, missions) folder and load editor and preview
you will notice AI crawl far too much!
if you change waypoint to stealth they like to crouch again
