Punisher artist Mitch Gerads was recruited to design the morale patch for the second annual Chris Kyle Memorial Benefit and Auction, which will raise funds to support the Guardian for Heroes Foundation.

Produced by ITS Tactical, the patch sports the iconic Punisher logo that served as the unofficial crest of SEAL Team 3’s Charlie Platoon, Kyle's unit. The limited-edition patch debuted Friday, but sold out so quickly that the Kyle family requested more be made available.

A Navy SEAL whose story was recounted in the memoir American Sniper and its hit film adaptation, Kyle recorded the most sniper kills in U.S. military history while serving in Iraq. Honorably discharged in 2009, Kyle was shot and killed along with one of his friends in 2013 while at a shooting range in Texas.

The patch can be purchased on the ITS Tactical website, with all proceeds going to the Chris Kyle Memorial Benefit and Auction. The event will be held May 1-3 in Fort Worth, Texas.
