Pc Terry was shot in the chest during a training exercise
A police force has suspended some firearms training after the death of an officer during an exercise.
Pc Ian Terry, 32, of Burnley, Lancashire, was playing the role of a criminal in a getaway car when he was shot in the chest on Monday morning.
Greater Manchester Police said it is now halting the use of the type of rounds fired in the exercise.
Meanwhile, Pc Terry's wife, Joanne, paid tribute to him and said his family "meant everything to him."
The Independent Police Complaints Commission (IPCC), which is carrying out an investigation into the incident, said officers were using Round Irritant Personnel (Rip) rounds, which are designed to stop vehicles containing armed criminals.
When fired, the rounds release a blast of CS gas at high pressure.
The IPCC has said, in this instance, the cartridges were filled with a harmless white powder rather than gas.
Pc Terry was not wearing armoured clothing when he was hit by the shell at the training centre in Newton Heath.
Greater Manchester Police said it was suspending all exercises involving Rip rounds until the outcome of the IPCC inquiry.
Other firearms training has also been suspended, but Greater Manchester Police says a decision will be made about those courses over the next few days.
Pc Terry joined the force in 1997 and had been a firearms officer for six years.
He leaves two children, Lauren, four, and John, three.

His family said in a statement: "Ian was the best dad. His children meant the world to him as did Joanne.
"He was everyone's best friend and he is just such a loss to everyone he touched.
"Ian lived for his family and his job. They meant everything to him and he loved them both so much."
They added: "We can take some comfort in the fact that he knew in return how much love and pride we, as a family, had for him.
"He had the same love, respect and pride from his friends and work colleagues.
'Worry about my brother'
"All his life Ian has been such a genuine and caring person that everyone who met him couldn't help being touched by his personality.
"He is such a great and tragic loss to his family, friends, colleagues and to society.
"It was typical of Ian that every time we told him to stay safe, because we worried about him so much, he would say: 'Worry about my brother Paul [a traffic police officer], because I know the dangers I'm facing and have back-up at my side.
"When he has to stop someone in a vehicle he doesn't know what's going to face him and he's on his own'."
