In the 4th Ed. AS:CE Urban Combat Section (pg. 72), the example provided in the Building Weight Capacity rules indicates the each level of that medium building has a weight limit of 2. The AS Buildings Table on page 73 has it listed as Weight Capacity (per 1" height).
I had someone say that a 2" medium building could support a size 4 'mech on the roof, and just looking at the Table I'd agree. Am I reading the rule and example wrong?
