The wife of one of the three Canadian soldiers killed in Afghanistan Tuesday says that she and her husband talked openly about the possibility he might die while serving in the war-torn country.

Mishelle Brown, wife of Warrant Officer Dennis Brown said she and her husband spoke for over an hour on the day he died.

"We talked about everything . . . some people say, 'I wish I had one more thing to say to them,' but I said everything, I don't have to say one more thing, I said it all when he was alive," she told reporters in St. Catharines, Ont. "Everyday I spoke to him I reminded him how important he was to me and how lucky I was to have him."

She said they spoke only about the possibility he would die in Afghanistan.

"Dennis was a realist . . . he made me prepare for his death," she said, adding that they discussed with their four children what they would do if he died in the line of duty. "And boy, did we prepare."

She said her children knew their father was killed when they saw the officers come to their home to inform them.

Brown was a reservist with the Lincoln and Welland Regiment in southern Ontario and served as a police special constable in civilian life.

Brown was killed along with Cpl. Dany Olivier Fortin and Cpl. Kenneth Chad O'Quinn in a roadside bomb in the Arghandab district Tuesday.

Brown's wife said she was told he was a hero, but that he was always "her hero."

Mishelle Brown said she wanted "the whole world to know what an amazing man he was."

"That's what's keeping me strong, I met my dream come true. Nobody can take that away from me. No roadside bomb can take that away from me. "

Brown was asked what she thought of Prime Minister Stephen Harper saying recently that Western forces could not beat the insurgency in Afghanistan.

"We may not beat the Taliban, but there are lots of things in our lives we can't beat," she responded. "You can't beat crime, but do you give up? Do you stop? Absolutely not."

The latest casualties brought the total deaths of Canadian soldiers in Afghanistan to 111.
