Kind of late to the discusion, but here's my 2 cents:
The missions for the Sea Services' helos are so wide and varied that you'd be hard pressed to find something more "tactical" to teach that would be applicable to all the communities. Should we teach night form? Night low level? Night SAR? Night DLQs? ASW? Gun Patterns? What exactly is it that the AF and Army are teaching that we aren't?
And for all the help that goggles can be, my community at the least, still has a 1hr night currency plus unaided DLQs and Vertrep. So the need for a solid night flying background still exists.
In the RAG, we didn't do too much in the way of tactical stuff. Just a few overland/form events. All of more involved tactical stuff is taught by the wing weapons school as it's required. While Navy helos are currently operating overland, this doesn't change the need for traditional Navy helo missions. and for every air ambulance det, there's still going to be a need for helos to run admirals back and forth, to vertrep that pallet of soda, to sit in starboard D and wait for Squid to punch out. Not exactly glamorous missions that require the wearing of tactical patches, but they're still important missions in the grand scheme.
