Has the Army reoriented yet from insurgency warfare tactics to heavy conventional warfare tactics?

I haven't seen any evidence of it either and that's worrying.

The Army started the transition to large scale ground combat back around 2015ish. They did this by switching the scenario at the Combat Training Centers (JRTC, NTC, MNTC). They have even renamed the villages in the training area from Arabic to European names and are working on remodeling so the building look European.

Somebody had better figure it out. Personally, I am reluctant to support any effort to focus on insurgent warfare. We wasted a lot of time (not to mention blood and treasure) fighting in Vietnam as an insurgency. It was an invasion and we didn't have any success until we began to engage the invaders. Then there's the question of what business have we interfering in a true insurgency? Our nation is founded on the premise that people (ALL people) have a right to "...abolish [their existing government], and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness." As for terrorists, they should be treated as pirates (criminals), and there's plenty of extant international law regarding piracy. We should enforce it.
