Ex-UFC fighter Tim Kennedy said he has re-enlisted in the US Army Special Forces to fight ISIS.
Kennedy was as an impressive in-ring fighter. During his amateur career he won 30 out of 31 matches and after turning pro he won 18 out of 24 matches.
He first started fighting in 1996 and finally announced his retirement earlier this year.
He posted a message to Facebook thanking his wife, his opponents, his fans and coaches for allowing him to compete for more than 15 years.
Now, following the 37-year-old's retirement, he wasted little time before re-enlisting with the Special Forces.
Back in 2004, as his fighting career was taking off, Kennedy took a break to join the US Army. After completing Ranger School he was assigned to the 7th Special Forces Group.

While part of the group, he was deployed to Iraq and Afghanistan on several occasions. In that time, he earned the Army's Bronze Star medal, which is awarded for valour under fire.
Following his time in the forces he went back to fighting full-time. But, since signing-up once again, he's posted a bunch of photos to Instagram showing how he's preparing for a potential redeployment.
However, of all the images, it has been this picture that has grabbed people's attention most.
Captioned it: "Dear ISIS, If you are lucky enough to kill a Special Forces operator, the possibility of us dropping the biggest non-nuclear bomb ever made on you should be the least of your concerns.
"There is a vengeance and wrath associated with the loss of one of our brothers. May God have mercy on your soul because we are coming and we will have none to give. Sincerely, The U.S. Military."
Tim has also told TMZ he's more than ready to get back out there: "I think that people like to do the things that they were made to do. God put me on this planet for this reason. There's nothing like doing what you love to do when you have the support and excitement and encouragement of your seniors."
He says he was waiting to see the outcome of the US Presidential election last November before he decided whether to re-enlist. While Tim doesn't publicly support Donald Trump, he certainly respects who he appointed as Defence Secretary, as well as National Security Advisor.
"When Donald Trump starts putting guys like General Mattis and General McMaster in my chain of command, dude, let me tell you how good my life is about to get."
