A former Green Beret captain says U.S. commandos in Somalia routinely dressed in Canadian uniforms and passed themselves off as Canadian troops. Defense Minister David M. Collenette described the claim as "very unusual" and told Parliament that military headquarters would investigate whether Canadian military procedure was breached. News agencies quoted retired Green Beret Capt. Dan Alvis as saying U.S. commandos in Somalia routinely masqueraded as Canadians. The head of Canada's armed forces, Gen. Jean Boyle, expressed surprise at the claim.
