"The Wolf Artillery will be bowing out in this update. In its place comes the Wolf Thug who comes with not one, but two Uzis! This agile unit’s sweeping attacks will make short work of any infantry within range."
The Wolf Thug is a soldier unit which has the useful ability to spray fire into a three-block wide target area, up to one row deep. The Thug is introduced in the 2.9 Patch, and is trainable in the Mercenary Vault for some Gold and some Merits.
At Rank 1, his bullets can majorly soak up armorless infantry, albeit often getting his bullets deflected, due to his not too high offense (40 at rank 1). At first glance this unit might be pretty useful, but with deeper analysis, because he is only useful in the first row, he is extremely vulnerable to almost all enemy units and must rely on above average defense for protection. Putting these in battle is a decision that you'll have to make on your own.
It is however useful in PvP against aircraft with its low value.
