Scenario: Russian Helicopter Attack on US Convoy?

If the Russians were not our Allies; Considering the Abrams and Bradley both have 50 Cal M2s and 7.62 coaxial machine guns and the Humvees would probably have SAWs or 50 cals and maybe a 40 mm granade launcher and a couple of AT4 rocket launchers; not likely to have stinger missiles because that is a expensive specialized weapon system. I would give the convoy the edge.
