> I know this is a side point to the OT’s main point, but after reading this, it made me curious. If Master Chief were to ditch the Mk VI in favor of a GenII armor set, while not being as durable, would his strength therefore also increase to even greater heights?
In theory, it is possible. However, the Chief’s long-standing policy is to choose the best available equipment can for the job. Thus, he is highly unlikely to trade the Mark VI’s “shields and armor are so vastly superior to Gen-II that it must literally be expressed in orders of magnitude” defensive superiority in exchange for a small boost in his strength. (I’m serious. The Mark VI’s shrug off so much more punishment than the stuff that Gen II’s are compromised/penetrated/overcome by that if Scrugg’s had attempted to pull a similar ‘gotcha’ moment on Chief, the end result would have been nothing more than Scrugg’s looking utterly stupefied as he holds an empty SAW, with 117 turning towards him, arching eyebrow behind his helmet, and saying something to the effect of “Okay, Son, you’ve gotten my attention, now what are you going to do about it?”*)
> To be fair, it would seem the UNSC has developed Super Knives ™. Not only do you see one pierce the gauntlet of the GEN2, but you also see it pierce the hull of a Lich and the eyepiece of the Didact’s helmet. :v
Do not remind me of that bit of idiocy. Ur-Didact’s armor is supposed to be a high end Forerunner combat skin that, even if it lacks shields for some reason, canonically shrugged off a pulse grenade detonating inside of it, something that can supposedly reduce a hunter, armor and all, to ash. Given that this is the same comic that has repeatedly demonstrated it cannot even get the basic biology of the characters/races in question right (including Ur-Didact himself), among a great many other issues with it compared to the rest of Halo canon, my in-universe explanation of it is that it is Facepalmer’s poor attempt at making a biography of the Chief and herself. Very much like how Captain Qwark’s plans are all shown, if you’re familiar with the Ratchet and Clank series 
> Was this in one of the comics? I have yet to read those. It would make sense, though. It could be that this is just the natural progression of the technology, as seen in the real world; a thing is made originally to last and to be used as long as possible with little repair, but in the name of production and weight/efficiency, the non-critical systems are stripped of heavier material and replaced with lighter, weaker material. Mark IV armor is seen deflecting needler and Covenant carbine shots in Forward Unto Dawn because it was armor, sans shields. With each progressive iteration after shielding is introduced, the base armor value of the physical equipment is reduced as shielding ability goes up.

> All a GEN2 set really seems to be is platform for the software, strength augmenting and shield emitter systems. There’s no real armor rating there anymore. It seems, from this perspective, entirely reasonable that with time MJOLNIR may become nothing more than a bodysuit interwoven with hardlight emitters with a helmet, power pack and boots.
It is from Escalations. However, it’s not just the armor that’s inferior, its the shielding systems as well. Scrugg’s guns down multiple (at least 2, possibly 3) Spartan-IVs, as well as a few allied Elites, and Brutes with what is heavily implied to be a single SAW magazine, and does so fast enough that no one has a chance to so much as utter a “Scruggs, what the yoink are you doing!?” or other such warning to the other Spartan teams. To put this in perspective, the Mark V armor the Chief wore during his trial run in TFOR, which has notably inferior shielding systems and armor to the Mark VI, tanked a number of 30mm rounds and only lost a quarter of its shields. Assuming that they’re using a 30mm round that is similar to the GAU-8 “Avenger” (and given that Ackerson was more or less trying flat-out to kill 117, we’ve no reason to suspect that he was in any way holding back), one, single, slug from those 30s would have had more power behind it than Scrugg’s entire 72 rounds 7.62 NATO magazine.
The Gen II’s are clearly little more than cheap knockoffs of the Gen I’s, that sacrifice incredible amounts of protection for the sake of being easier to produce.
*Well, not really. Such a thing would be wildly out of character for the Chief but it’s funny to think about. More realistically, it would have ended with him speed-blitzing Scruggs, disarming him, and then painfully disabling him (disabling, not killing. After all, you can’t interrogate a dead man to find out who he’s working for. A lesson that a certain self proclaimed Commander Most-Awesome-Spartan-Ever really should take to heart).
