A military prosecutor asserted the proof of Gallagher's guilt is his own words, his own photos, and the testimony of his fellow troops, while defense lawyers called the case a "mutiny" by entitled, junior SEALs trying to oust a demanding chief.
"I've made mistakes throughout my 20-year career - tactical, ethical, moral - I'm not ideal but I've always bounced back from my mistakes".
The decorated Navy SEAL who was acquitted of murder in the killing of a wounded Islamic State captive in Iraq thanked Fox News, President Donald Trump and two congressmen for their support during his trial.
Gallagher was found guilty of posing for unofficial pictures with a human casualty and is to be sentenced on that charge later in the day.
His wife, Andrea Gallagher, who was behind his side throughout the court-martial said she was elated.
Gallagher also was charged with attempted murder in the wounding of two unarmed civilians - a schoolgirl and an elderly man - shot from a sniper's perch, as well as with firing deliberately on other non-combatants and with obstruction of justice.
Gallagher could face up to four months imprisonment for the single conviction along with a reduction in rank, forfeiture of two-thirds of his pay and a reprimand. "Next time it happens, I'll do it somewhere where you can't see".
Gallagher also got credit for 201 days of pretrial confinement. John said Gallagher should have stopped the photos from being taken. The sentence also carries a two-month forfeiture of his salary, a sum of almost $5,400. "Glad I could help!" the president wrote.
"This has put a black eye on this community, but I want the nation to know that this is not what our community is about", Gallagher, who appeared on Fox News' "Fox and Friends" Wednesday with his wife Andrea and his attorney Tim Parlatore.
Speaking of his accusers, Gallagher said, "this small group of SEALs that made a decision to concoct this story in no way, shape or form represent the community that I love". Hunter is from California and Norman is from SC.
Gallagher insisted that disgruntled subordinates with no prior battlefield experience fabricated allegations against him over grievances with his leadership style and tactics. They said the lead investigator built the probe around their stories instead of seeking the truth.
Before eventually reporting their commander in March 2018, Gallagher's platoon members said they had gone to great lengths to stop his alleged carnage of civilians, reportedly tampering with Gallagher's rifle so he could not shoot them at will.
In a surprise blow to prosecutors during the first week of the trial, a Navy SEAL medic testified it was he, not Gallagher, who caused the death of the gravely injured prisoner by blocking his breathing tube, calling it a mercy killing.
The defense said it was just gallows humor and pointed out that nearly all platoon members who testified against him also posed with the corpse. "Got him with my hunting knife".
The seven-person military jury, which included five Marines and two sailors, delivered the verdict after about eight hours of deliberation.
