In an Ammy fight solid grappling and wrestling is lethal. As Halffrag said make sure you are matched up well. Make sure the guy you are fighting has around the same record.0-0,0-1,1-0 along those lines.
Best way to gauge this. When you can go 3 5 min rounds in sparing you are pretty well ready. Cardio is another killer.
