The Calvin Gibbs Court-Martial: Leader of the Maywand District “Kill Team”
On this page
Army Staff Sergeant Calvin Gibbs, a squad leader in the 5th Stryker Brigade, was the highest-ranking of the five soldiers charged in the killings of three unarmed Afghan civilians in Kandahar Province in 2010. On November 10, 2011, a five-member military jury at Joint Base Lewis-McChord convicted him of three counts of premeditated murder and related charges. The related charges included cutting body parts from the dead and planting weapons to make the killings look like combat. He was sentenced to life with eligibility for parole. The planted weapons became evidence of premeditation. And the theory that reached the squad leader made him a principal for killings he did not personally carry out.
The Gibbs Record in Brief
| Item | Record |
|---|---|
| Accused | Staff Sergeant Calvin Gibbs, squad leader, 5th Stryker Brigade, Joint Base Lewis-McChord |
| Forum | General court-martial; five-member jury that deliberated about four hours, according to ABC News |
| Plea | Not guilty |
| Findings | Guilty of three counts of premeditated murder and related charges, including taking body parts and planting weapons |
| Sentence | Life with eligibility for parole; reports gave the eligibility point as 10 years (CNN) and eight and a half years (Al Jazeera) |
| Main witness | Jeremy Morlock, who had pleaded guilty and received 24 years under a cooperation agreement |
| Later litigation | In January 2020, Army Times reported a federal lawsuit seeking to vacate the convictions after the Army Court of Criminal Appeals' 2018 decision |
What the Jury Found
CNN reported that the court-martial “found Gibbs guilty of murdering three Afghan civilians, illegally cutting off pieces of their corpses to keep as ‘souvenirs’ and planting weapons to make the men appear as if they were Taliban fighters killed in legitimate firefights.” Al Jazeera reported that Gibbs “was convicted on three counts of premeditated murder in the slayings of Afghan villagers last year that were disguised as legitimate combat engagements.” ABC News reported that he was “also found guilty of 12 related charges, including taking body parts as trophies from corpses.” Gibbs “testified in his own defense, denied murdering civilians, but did admit to taking trophies”.
Premeditation and the Staged Scene
Article 118(1) covers a killing by a person who “has a premeditated design to kill”. Premeditation is a state of mind, and it can be proven through circumstances. In the Gibbs case, the planted weapons supplied those circumstances. A weapon carried in order to be placed beside a body is preparation for a killing that has to be explained afterward. That preparation is evidence that the decision to kill came before the act, which is what separates premeditated murder from a split-second battlefield decision.
The same facts also defeat the combat explanation. A soldier who fires on a person reasonably believed to be an enemy fighter is not committing murder. Staging a scene to create that appearance after the fact is evidence that the appearance was false.
A Leader’s Liability for Acts Others Carried Out
Gibbs did not personally carry out every killing. The 2020 Army Times report on his lawsuit noted that “Gibbs was not directly involved in the first killing, according to multiple accounts.” The government’s theory reached him through two doctrines. Under Article 77, one who “aids, abets, counsels, commands, or procures” an offense is a principal. And under Article 81, the Manual says “Each conspirator is liable for all offenses committed pursuant to the conspiracy by any of the co-conspirators while the conspiracy continues and the person remains a party to it.”
The key testimony came from a cooperating insider. Al Jazeera reported that “His chief accuser was the ex-corporal described as Gibbs’ right-hand man, Jeremy Morlock, who pleaded guilty to murder for his role in the same three killings”. The 2020 lawsuit, as described by Army Times, argued that “Although Morlock initially told CID during a videotaped interview that he did not witness Gibbs commit any offenses, Morlock later testified at trial that Gibbs gave him a grenade to toss at the first Afghan”. The lawsuit’s attack on the testimony is a standard challenge to accomplice evidence: a cooperating witness who changes his account after a deal.
The Appeal and the Federal Lawsuit
The 2020 Army Times report quoted a 2018 opinion of the Army Court of Criminal Appeals: “As with any complicated, multiple-witness trial, there are inconsistencies in the testimony and evidence presented”. It reported that the Army appeals court decision “paved the way for the case to move to federal court and out of the military justice system”. Gibbs then filed a lawsuit “to have his convictions vacated.” The report also described his defense counsel’s claim that, had certain witnesses been introduced at trial, “the jury could have found Gibbs not guilty of the six most serious charges”. That claim is an argument in the lawsuit, not a finding.
Where Gibbs Fits Among the Others Charged
| Accused | Resolution | Reported sentence |
|---|---|---|
| Spc. Jeremy Morlock | Guilty plea with cooperation, Mar. 2011 | 24 years |
| Spc. Adam Winfield | Guilty plea to involuntary manslaughter, Aug. 2011 | 3 years |
| Pfc. Andrew Holmes | Guilty plea, Sept. 2011 | 7 years |
| Staff Sgt. Calvin Gibbs | Contested trial, Nov. 2011 | Life with eligibility for parole |
Staged Combat and a Leader’s Liability
The law allows soldiers to use deadly force against enemy fighters. It does not protect killings that were planned and then disguised as combat. In the Gibbs case, the staged evidence became proof of the premeditation it was meant to hide. And a leader who organizes others to kill is a principal under Article 77 even for the killings he did not carry out himself. Whether that liability was properly proven in his case is what the post-conviction litigation contests.
