Ok I think a link is now working to the stat wars at-te's I using. The small one is model from eBay, costs like 10.00 to 15.00 with shipping. The larger one will be a command version, and I will mount some battle pods arty on it. Pictures will follow as I move forward.
The smaller one I invision as a 2 man tank used to support infantry units. These things chew up urban terrain and move at the same speed as the squad. The top laser should be along the lines of the officers pod cannon or so. I have yet to play test these rules so they are offered only as a starting point. A single one should cost 20-25 points added to infantry squad, or in a support unit of 2 for 40 or 3 for 60..
If anyone plays tests let me know. They are based on 120mm bases. This is meant to force the tank so breach a path as it moves as Most streets won't be wide enough.
