Ruffian

Ruffian is a tier 5 tank that upgrades from Interceptor at level 60.

Design
The Ruffian looks like a Destroyer with a non functioning Flank Guard jammed in the cannon. The flank guard is facing backwards, with its rear 2 barrels shown so it wouldn't be confused with Interceptor.

Technical
The Ruffian shoots powerful bullets with roughly the stats of a Destroyer. These bullets have Flank Guard turrets on them.

As the Ruffian

 * This is generally not used, but it is good for farming. The main benefit of the Flank Guard turret is that it will not inflict recoil on the bullet, keeping your shot inline with where you fired it.
 * Don’t forget: this is basically a Destoyer, so your bullets will still one shot almost any tank.
 * If you miss, like all Interceptors, the turrets can still do their job.
 * Using your recoil to catch up to enemies if they try running is highly recommended here; especially considering many people probably won’t know what this is.

Against the Ruffian

 * Cruiser branch can trip it up well, unless you let the turret destroy you.
 * Using something like the Moderator, you can easily take the Ruffian down; and most Destroyers actually.

Trivia

 * This, the Nectarine and the Deviser are the only tanks whose ammunition has Flank Guard turrets on them.
