Hrrm. I respect your wantings to create a survival suit based around a more primitive time, but you must not let visuals overtake necessity.
As you can see, I have done away with those wings altogether, which couldn't support your test subject or design unless the both were around 15-20 kilograms. I have substituted the wings with a jet pack, which should do nicely.
Hmm, yes, you should want a visor then for all of this flying around, which I have supplied in the red line. It should do perfectly for detecting complex machinery (obvious targets for termination) so that you may know where your targets lie without having to shorten the distance gap. It should also keep the wind out of your eyes.
Yes yes yes, grenades. Check. Can never have too many. Some gold titanium alloy "Ironman" armor could come in quite handy (very malleable, very easy to work with, yes), and I suppose to keep your primitive theme you can carry a sword. I was about to upgrade the sword to a GH-Harrison Ion Rod, but that might be a little too pricey.
Send me the field testing results!
