From Q's drop today:
32536AA00: _ MI TM (UTAH)(STRAT SIGINT):
32536AB00: _ MI TM (OCMC)(STRAT SIGINT)
32536AC00: _ MI TM (DET A)(STRAT SIGINT)
These three Army units allegedly support NSA. The first provides IEW (intelligence and electronic warfare) operations to NSA's Utah Detachment. NSA operates a massive electronic data storage facility in that area. .
The second provides IEW operations to NSA's OCMC (Overhead Collection Management Center) Detachment. These guys manage surveillance from satellites.
The third provides IEW operations to NSA's Detachment A. Haven't figured out what they do yet.
