"Never trust a woman who paints her tank red."

Sergeant Alabama "Bama the Hammer" Kowalski is a Terran Dominion siege tank operator. She is said to be so accurate with her tank's shock cannon that she can drop shells inches away from friendly forces without harming them.[1] A "rough and tumble Southern gal," Kowalski takes great pride in her tank, as well as her rank.[2]


The following section contains information from Heroes of the Storm that is ambiguously canonical.

Kowalski has served some of the toughest tours around the Koprulu sector. The thunderous roar of her siege tank's shock cannon strikes fear right into the heart of the toughest of warriors...including some of her allies.[3]
