As Rotary Shield
The Rotary Shield is a master of single combat and easily beats power bullet tanks like the Destroyer branch. Wait for their shot, block it, and counterattack while they're vulnerable. Remember you can only face one tank at once. If you're locked into combat with a Tag Team or especially drone classes, get against a wall to up your chances.

Against Rotary Shield
Its shield is useless when attacked from multiple angles. Tag-team on them or use a tank from the Director branch to mess them up. This will be harder to pull off if against its superiors Double-Defence or Auto-Shields, however.
