I managed a tac vic the first time around, but that outcome shoudn't lead you to believe it's an easy scenario. Far from it. For the first 10-15 turns it was touch and go, especially around roadblocks 1 & 2. I didn't capture roadblock 3 until the very end.
My most valuable unit, believe it or not, was the jeep I got with the first reinforcements. I used him to shuttle zook and MG teams to the two forward roadblocks. They arrived in the nick of time, allowing my depleted units to hang on.
IMO An excellent scenario.
