I used to fix executive transport H-3s, green, but no white top. I imagine they could carry some soft armor, but not a lot, guessing the VIP interior, all the comm and ECM stuff already has Marine One weighed down. A guess, because that's about what I know about HMX-1. I thought I would go check it out when I was on Quantico once. After a quick look at the security and the we will shoot you signs I made an effort to not look at the buildings, drive completely correct and get back to my hotel. I spent some time next to DEVGRUs compound and that was nothing compared to this.
Years ago I got to see the "shell game" with Bush #1 except with H-53s. Pretty neat, willing to bet the ones without him on it were pretty heavily loaded with miniguns and angry Marines. Saw a similar shell game except with black SUVs as they passed me on the interstate. Laura Bush convoy. Rear windows down on a couple with agents sitting in the trunk monkey position, I assume with a belt fed. Shoot at a few more helos may well be eff around and ind out territory.
