My account username is DSS665. I saw no ranged units. Bombers are possible but there were 4 cruisers in one location and 5 artillery in another that were taken out in a span of a few hours. They would have had to have a large fleet of bombers to take out all of these and leave no evidence.
I won the ground battle with 25 troops and 2 tanks. I don't see how they could possibly have taken out my ranged troops that quickly.
