Is it plausible to depict the Segmentata using armor upgrades?

[Philippus Flavius Homovallumus]

Once again, the modern infantryman cant use light of any kind at night, because it would give his position away. But we were still expected to keep our 782 gear and weapons clean and serviceable. And we didnt have all day to do it (way too busy closing with and destroying the enemy and such).

Your belt kit is made out of synthetic webbing, unlikely the snap under stress, your body armour won't suffer from random failure of it's fittings, which aren't made of bronze.

THe analogy between modern and ancient is bad in most respects, in some it works. Soldiers will generally do the bear minimum of work to stop themselves getting killed, for instance.
