I decided to try my hand at the french light tanks. I had almost enough free exp to make it to the AMX 40 so I bought an AMX 38 figuring I build up the difference. What a slow POS that one is. I think I'll just wait for my free exp to build up instead of wasting my time with it.
I'm also pretty close to having the credits to buy a M36 Slugger so I may be doing the TD thing soon.
I'm liking the T20, but it's expensive to fix when I die. Not a good combo when you are grinding for credits.
