Depends where they're going. No end of scenarios where helicopter / jeep isn't going to work, or are being shot up, or can't fly. Yomping 50 miles across rough terrain, over 3 days with 100lbs and capability to fight when they arrive probably isn't a capability you want to scale back. It's used too often. There's good reason it's a usual part of the combat fitness test for recruits.
