To add to this: taking territory is the easy part.
The hard part is holding it, because you don’t just have to worry about staffing the front line, but maintaining security in the occupied regions long enough for non-state actors to cease hostilities and accept the invading force as the new legitimate authority- which may never fully occur- all the while dealing with resistance fighters.
This means orders of magnitude more personnel, funding, and equipment for an unknowable length of time across a much larger area than just the line of incursion.
It’s taken them two years to fail to take the land, and now have an incursion into their own soil to contend with. so I’m skeptical they’d manage to keep it permanently.
Some states don’t require observation of heat stroke risk mitigation for their workers. Getting it into their federal labor contract ensures a) the feature will be required as a functional feature in all their vehicles, and 2. they can’t be told not to turn the feature on.
