"Military" Bead vs Commercial Bead

Quick question. I know a couple months ago someone schooled me on the differences in beads from one type of tire to the next. I couldn't find that convo when I searched so I figured someone could answer this quick. I know that commercial tires have a different type of bead than consumer tires. As far as I know, Military tires like XZL or MVT have a commercial style bead.

So what does the Continental MPT use?

I've seen someone who has 1st Attack Super single wheels on an F450 and hes running 35" Nitto Tires, with plans to upgrade to MPT 81s. I wasn't aware Nitto made 20" tires with commercial beads, so is that the case, or do the Continental MPT 81s use a consumer style bead?
