Help on Second Russian Level

[Daktor]

I'm not sure what the difference is.

For comparison:

Hard: attacks start with light tanks, move to 50mm, then finally medium 75mm tanks. Waves start with 1 tank and about 5-10 infantry, then 2 tanks and ~15 infantry, final waves are 4 tanks with about 20-25 infantry. There was usually about 2 - 3 minutes between waves except for at 75% when there was a reprieve of about 4 minutes.

Final Score: 940 enemy infantry killed, 39 enemy vehicles destroyed
