'Gilman's is correct also for Hatch's Fantasy Grand though not all different-armies Chesses.'
I was actually referrng specifically to the family of armies replacing the Queen, Rook, Bishop, and Knight of FIDE Chess on the 8x8 board with pieces designed to equal their combined values - the Nutty Knights, Pizza Kings, et cetera. As far as I am aware, the Immortal AntiClericals are the first army proposed for this system that substitutes different pieces for one kind of FIDE piece.
