I've seenm an article on the combo the Marines are doing--some traditional exerises, and then a test with field-relevant exercises. It seems quite relevant to what one might do in combat. As usual, the army is behind in implementing something with an edge (see also MC martial arts vs. army bjj training!).
Marines do the Combat Fitness Test with the following:
1. 880 Yard Run. Marines will run for 880 yards while wearing boots and camouflage uniform (pants and t-shirt).
2. Ammo Can Lifts. Marines will lift a 30 pound ammo can from the ground, over their heads as many times as they can in two minutes.
3. Manuever Under Fire. Marines must move through a 300 yard course, and perform designated tasks, in the time limit authorized. The tasks include:
•Moving in a quick scurry for 10 yards, then a high craw for another 15 yards.
•Drag a casualty for 10 yards, while zigzagging through several cones. Then lift the casualty and carry him/her at a run for 65 yards.
•Carry two 30-pound ammo cans for 75 yards, while zigzagging through a series of cones.
•Toss a dummy grenade 22 1/2 yards and land it in a marked target circle.
•Perform three push-ups, pick up the two 30-pound cans and sprint to the finish line.
