User blog comment:General B.H./Arc Troopers vs Ultra Elites/@comment-9374378-20130604101712

Yes energy sord. Ever played halo 2 all the ultra elites use them as there secondary weapons in halo 2 ( by switching to energy sords when you destroy their shields. A few use them in halo reach.

Zealots, Ultra Elites, Elite Honor Guards , and a few stealth elites use energy sords.

Halo 2 ultra elites are my second favorite elites but halo reach and halo ce golden zealots are my favorite.
