Most Canadians call the E.R.T SWAT. Way easier to say SWAT and frankly, most Canucks recognize SWAT over ERT.
Mind you for me as a kid it was a member of the special weapons task force. No sense of humour. As a 13 year old kid I was chased into a 24 hour grocery store by some drunken teenagers. My BB gun was no match for four drunks and a pickup truck. Long story short when the manager called the police to declare there were men with guns in the store it really excited the small sleepy yokel police department who were sadly disappointed with two scared 13 year old kids were the gunmen. It was a CO2 bb pistol but still….no assault rifle.
