I would just say, sir, that I think you're on to something. I don't think Canada has to have identical equipment.
What we find in the field is that often Canada is there, especially outside of North America, in small enough numbers that it needs to work within a larger American or British command. We've seen that in a couple of cases, and shared equipment can make maintenance, providing spare parts, and other upgrades possible. So there are advantages to interoperability. But I agree, it's not a prerequisite that the equipment be identical or, referencing the earlier question, that they be bought in the same model year, as long as there is a mutual understanding of the technology and we're able to support one another.
