Adjacent units were informed and coordinated with, before an operation commenced.
In Trump's Iran war of choice case, US units, not involved in the actual attack were not even informed, either, costing lives on day 1, at a tactical operations center, that was acting as a fixed base, not a Tactical Operations Center, at all, as doctrine calls for TOCs to be mobile, not fixed for years at a time, allowing for pinpoint targeting of the known fixed location. Fixed is nice if you work there and feel you are under no threat or not informed you were under imminent threat, as left out of the intel loop. It just not tactical.
One ally country actually shot down one of our fighters, with missiles we gave them for their air defense, as that idiot and Maj Hegseth (FOX News idiot) did not even coordinate overflight. There are a lot of benefits to having allies, you trust, and not giving missiles to allies in name only, that cannot be trusted. Then of course, there is the go-it-alone method, and we see how that worked. Coalitions are proven to be better.
