SAS troops are reportedly using the Punisher logo after making their first kill.
The skull logo is famous as the marking used by the Marvel character Frank Castle in the popular series, comics and films.
However, reports claim that soldiers have adopted it, attaching it to either their helmet or body armour after having notched their first fatality in combat.
The practice had previously been banned in the SAS after members of the unit complained that it was disrespectful.
However, according to The Daily Star, the new Director Special Forces, who had also worn a Punisher patch during operations in Iraq and Afghanistan, has said there is no problem with it.
A source told the publication: "The Punisher badge has been adopted by the regiment and shows that a member of the special forces has been blooded in battle.
"When the badge was initially banned there were many in the regiment who thought that the unit was going to fall victim to political correctness.
"But fortunately someone has seen sense. The special forces are often sent on very dangerous missions which often involve killing people - that is a fact of life.
"The badge is a simple acknowledgement that an individual has been in action and achieved a kill in combat.
"It is like saying, 'Congratulations, you are now a member of a very elite club.'"
This isn't the first time the symbol has been brought up in recent weeks.
Jon Bernthal, the actor who played Frank Castle/Punisher in the series, recently criticised the rioters who wore the emblem during the attack on the US Capitol in January.
Speaking on the Independent American's podcast, he said he was utterly 'disgusted' and 'horrified' by the sight.
He said: "How folks could have gone and done what they did on that day is just something I can't wrap my head around, and the fact that symbol is at all tied into that is something that I'm horrified by and disgusted with."
He went on to say: "It's all about flag-waving and rhetoric and bulls***.
"I truly believe that people who have walked the walk, people who have actually been in combat, people who have actually sacrificed, people who have really lost - you know, that's really what that symbol is about.
"And I think people who have been in that valley understand that it's about proximity - it's about coming together, not about drawing apart.
"And everything that happened on 6 January... all that was about was divisiveness and pushing people away."
