Edward Gallagher faces a plethora of violations of the Uniform Code of Military Justice for actions while deployed in Mosul, Iraq, in 2017

A Navy SEAL is facing multiple war crimes for stabbing an injured teenage ISIS fighter to death while deployed in Iraq.

Special Operations Chief Edward 'Eddie' Gallagher, 39, is in custody facing multiple charges including premeditated murder and attempted murder for allegedly slicing the combatant's throat with a hunting knife.

The 39-year-old also posed next to the militant's body for photos n Mosul in May, 2017, prosecutors claim.

He has also been accused of performing a re-enlistment ceremony alongside the corpse and in front on American flag, according to prosecutors.

Afterwards, Gallagher allegedly text a photo of the body to a fellow SEAL, writing: 'I got him with my hunting knife.'

A couple of months later, he also allegedly fired at a male and female noncombatant.

If convicted, he could face life behind bars. He has denied all the allegations. His wife and the mother of his children, Andrea, also said in an interview: 'This is not who Eddie is.

'He is a lifesaver. He is that guy who runs into the burning building when other people are running out.'

Gallagher, a sniper and a medic, has served overseas in different deployments for 19 years.

After his latest tour, he was named named the top platoon leader in SEAL Team 7 and nominated for the Silver Star -the military’s third-highest honor, the New York Times reported.

However the disturbing allegations from the same deployment have since come to light.

Gallagher is said to have 'with premeditation, murder a wounded male person' under his care by 'stabbing him in the neck and body with a knife,' CNN reported.

The charge sheet, released on Friday, details that it took place in Mosul in May 2017.

Tamara Lawrence, public affairs officer with the Naval Special Warfare Command said the allegations are being taken very seriously.

'We train and operate in dynamic, complex and ambiguous environments and our operators are empowered and trusted to independently make difficult decisions during missions,' she said.

'They have consistently proven that their empowerment and trust is warranted. Allegations that indicate otherwise are, and will continue to be, investigated by the appropriate military and law enforcement authorities.'

Gallagher was also charged with shooting a man and woman near Mosul in June and July of 2017. Both of those people were said to be noncombatants.

If convicted, he could face life behind bars. He has denied all the allegations. His wife and the mother of his children, Andrea (pictured), also said in an interview: 'This is not who Eddie is'

The man - who is married and has children - was charged with obstruction of justice for 'attempting to discourage members of his platoon from reporting his actions while in Iraq' once back in San Diego.

Gallagher was charged with 'wrongfully' posing in a photo 'with a human casualty.' The man was also found to have wrongfully completed his re-enlistment ceremony next to the corpse.

He was said to have flown a drone over the human casualty, as well.

Gallagher was found to have been using the painkiller, Tramadol Hydrochloride, while in both Iraq and San Diego. The controlled substance is similar to opioids.
