[Halo] Is the fact that the UNSC fields mixed gender forces remarked upon as novel by the Covenant?

In the UNSC both men and women serve together in the interstellar armed forces (including direct combat arms like the infantry as well as the SPARTAN forces) and it's not seen as a particularly hot-button issue like it was in the 20th and 21st centuries.

Covenant forces, particularly Elites and Brutes, seem to be universally male (save for species without distinct sexes like Hunters and Engineers) and what we know about civilian populations of the Covenant seems to indicate very entrenched gender roles (as well as other weird stuff like the Elite's hatred of doctors). They obviously come into close contact with our forces and I'm curious if they think it's weird that humans seem to less socially uptight about that sort of thing.

The Covenant seem pretty far-reaching in their exploration and familiar with many sentient species.  It probably wouldn't seem that weird to them that humanity is composed of two genders and that both genders are capable of combat.
