This is just my relatively uninformed evaluation, but it seems to me like the planning of the invasion of Grenada was pretty haphazard and there was a lot of potential for serious screwups. Poor intelligence seemed to hamper the operation from almost the very start (most notably in the ignorance of the location of half of the American medical students), and poor coordination between the different armed services resulted in quite a lot of miscommunication and a number of friendly fire incidents.
In light of these facts, are there any potential PODs that might result in Operation Urgent Fury turning into something of a total disaster with sizable American casualties on the ground and/or American civilians taken hostage?
