I think you missed the part where I said that the people I spoke to are in the CAF - Canadian Armed Forces.
Specifically, our mechanized infantry. These are the people who trained the modern Ukrainian military, and CAF tactics form the backbone of their approach to warfare.
So no, I'm not assuming a specifically US style of warfare. I'm assuming an approach that fairly closely mirrors that of the experienced infanteers I spoke with.
And, again, this is their knowledge I'm relying on, not my own. I'm just trusting the actual experts on this one.
