And found that if you really know how to play this game, then on certain missions, all you need to succeed is but one unit. Whether it be a vehicle, grunt, or veteran. Sure you won't get any good rankings, but the idea is to make it challenging and a test of your skills.
Missions I beat with one Unit alone:
- Dune Sea Campaign: Gunships of the Desert - Unit: Missile Vet
- Dune Sea Campaign: Operation Black Gold - Unit: Mortar Vet
I haven't tried anything else out yet, but when I do, I will post my victories here. I suggest you guys try and beat these missions with only one unit, it's fun.
