A Boston police officer shot in the face by a suspect last year and the colleagues said to have saved his life by rushing to his aid, returning fire, and killing the gunman received the state’s highest award for policing on Sept. 22. Officer John Moynihan, who is still recovering from his injuries, Trooper William Cameron and the Boston Police Department’s Detective Brian Ball and Officer Brian Cameron were all awarded the Trooper George L. Hanna Medal of Honor in an annual ceremony that recognizes police for acts of bravery.

This year’s ceremony honored 22 police officers -- 11 from Boston, four from Bourne, two each from Tewksbury and Webster, one from Chelsea and two state troopers.

“Let’s not kid ourselves, very little about police work in this day and age out in the field is ever routine, because the mundane can turn into mayhem at a moment’s notice,” Gov. Charlie Baker said before presenting the awards.

Bourne officer Jared MacDonald also received the Medal of Honor, the highest of three tiers of awards. On Feb. 5, 2015, MacDonald was among a team of officers who responded to a car fire and shooting at an apartment complex, discovering a series of improvised explosive devices after they arrived.

After rifle fire broke out, MacDonald was shot once in the back, and two fellow officers -- Detective Sgt. John Stowe Jr. and state Trooper Nathan Monteiro -- carried him to an ambulance through waist-deep snow.

Stowe, Monteiro and the two Bourne officers who apprehended the suspect, officer Joshua Parsons and Sgt. Wallace Perry, received the Medal of Valor, the second-highest award.

Chelsea officer Joseph Capistran, Webster officers Robert Ela and Timothy Whiting, and Tewksbury detectives Edward Jackman and Michael McLaughlin were also presented with the Medal of Valor.

In Tewksbury and Webster, the officers fatally shot armed men. Jackman and McLaughlin were honored for their response to a stabbing outside the Salter School, an adult vocational school. Ela and Whiting were recognized for their response to a domestic disturbance in which a man shot at them outside his girlfriend’s house.

Eight other Boston officers were honored.

Officers James Conley, Janet Lewis and Dennis Medina were awarded the Medal of Valor for their roles in the March 2015 shooting in which Moynihan was injured and suspect Angelo West was killed. Also receiving the Medal of Valor were Detective Todd Hartgrove, for his standoff with an armed man threatening two women on a playground; and officers Reivilo Degrave and Gregory Eunis for their response to a Dorchester shooting. Officers Kevin Plunkett and James Walsh received meritorious recognition for their arrest of an armed man during a traffic stop, in which the officers fell into the street during a struggle and Plunkett was injured.
