This strategy involves building for a while at tech 1 then upgrading your factory straight to tech 3. This is effective because you can often flood the enemy with tech 3 units while they are still at tech 2, but often requires that you fight an uphill battle until you can use said tech 3 units. It also requires that you (over)extend yourself to gain the required resources to be able to skip tech 2. If anyone has an improvement to this strategy then please edit this page.
