As those who read the comics know, Rocket Raccoon is a tactical and weapons expert, but so far Guardians of the Galaxy previews have shown little of his skills beyond his wickedly sharp tongue.
 
The latest clip focuses on his well-known MacGyver ability to escape any situation with his fur intact.  Be sure to pay attention to what happens in the background around 0:45.
