Backwards thru the Valley 1.1

Eagle 6 this is Hawk 6 - approaching Area Alpha. Awaiting orders. Hawk 6 - Eagle 6. Good job gettin' there so fast. Deploy your unit and conduct a retrograde operation. Prevent enemy units from crossing into Area Bravo for at least 12 minutes. This will provide follow on friendly forces time to set up a hasty defense in BP Cobra. Be advised that a platoon of Leopard tanks from the 121'st PzrGren Bn Company E is in your area and is all that's of the force defending the entrance to the valley. They've been given your call sign and signal frequencies and are awaiting your orders. They're pretty beat up, low on fuel and have been fighting continuously for the past 18 hours. Hammer 6 - 3 tubes of heavy mortars have been assigned to you in direct support and are now on call. Enemy force is a Category A Soviet Tank Bn. They've been spotted coming right down the valley headed SW. These guys appear to be a fresh unit and consist of two companies of T-80s and one company of BMP's. Expect that they'll have heavy artillery and plenty of it in direct support of their attack down the valley. UPDATE: vs 1.1 Tweaked Time Limit, default blue plan, victory conditions, red units and plan.
