Army 25P (microwave systems MOS) is still around iirc (at least in the Reserves), and speaking from personal experience, 25Q10EAC was still getting dedicated 10 week training on tropo and DGM enclosures in 2012 at AIT.
That EAC rider was certainly rare, but we were told tropo was still in play in South Korea, and as late as 2015, another company in my reserve ESB had a few tropo systems they were still maintaining and training on.
But yes, by and large, most microwave-based signal MOS were rolled into either point-to-point "multichannel transmissions" (25Q) by which a good part of your qualifications include deployment of satellite transportable trailers (STT), SMART/T systems (shared with the Marines),and the Phoenix system; and the dedicated SATCOM MOS (25S).
