Elite armor for legendary edition?

In interviews the development talked about the customization. My question is probably dumb, but can you use elite armor in single player or at least firefight? Thanks ahead of time.<!–Session data–>

I don’t believe you can play as a Elite in the Single Player, but I believe you can in the Firefight vs Mode.

Elites are only featured as playable models in Invasion, Covenant Slayer, SPARTANs vs Elites, and Firefight Versus.
