I've not heard that before either, but I'd never heard "check gear down"
before I flew into a military field either. And this was in a 182 which

I've heard "...check gear down, no landing light observed" on short final at
RDU, a non-military airport. My landing light was inop and anyway is not related
to the gear position. Nevertheless I thanked the controller for his concern.
