you dont need very long to build many tanks
I know an order that let you build around 20 tanks in something like 7 minutes. then keep building more after that
8 on depot
10 on gas
11 on barracks
14 on factory then another depot
17 on another factory
then keep building tanks [img]smile.gif[/img]
I always remembered swam of tanks fighting against each other (in shareware, my terrain vs another player, this is his building order)... nightmare
