Y'know, if
Little Birds and
Blackhawks are good enough for
Delta Force and the
Night Stalkers, why aren't they good enough for Butei? Both handle well and would attract somewhat less attention than a Hind - we already see that Butei in Tokyo has Blackhawks - or at least access to the same - and the JGSDF operates OH-6s as scout helicopters, so bringing in MH-6s is a possibility.
And if you need firepower, well there's always the Direct Action Penetrator variant of the Blackhawk, with miniguns and rocket launchers, as well as the AH-6, of course.
Side note: after recovering from his injuries sustained in Somalia, Michael Durant returned to service with the Night Stalkers, switching over to the AH-6.
