Canada has always, and will always be someone's side kick. Equipment commonality just makes things easier. We don't have the national desire to be more than a middle power.
When you're talking an Arleigh Burk, sure. A tanks not so much. Take into account all the personal, crewed and equipment we already use of theirs (M777, CF18 ect ect) I think crewing is an issue only in extreme scenarios, which we have already ruled out.
The CAF and Canada need to stop thinking we have some sort of unique set of requirements that demands we R&D and produce our own stuff.
Army uniforms are a good example, if it works for Norwary or Sweeden it will probably work for us.
CRCNs talk about the new Subs was refreshing. What ever we get is coming as manufactured by the home nation. If we have to buy everyone converters to plug things in, so be it. The meaning is we are done with Canadianization. Get the solution available.
My understanding is the K2 is essentially a derivative of the Abrams. I stand to be corrected.
Either way, the current temperature means spending any treasure on American made products is going to be a difficult sell, and rightfully so.
