Whilethis is an old thread I'll give an update. I helped instruct a level 1 course about a year ago. Now they also teach weapons retention, some knee strikes from the clinch and half Thai clinch, and ways of maintaining distance from an attacker trying to close on you. I have no complaints now. I'm going through level 2 right now and it builds on the same groundfighting drills while adding in takedowns and knife fighting. Again no complaints. It's particularly good for the Army as we need good grappling skills do to all the detainee operations, security and Police type work we do. Not everything can be solved with beating the guy to death.
