Mind, that not even the URF, which was the most well-equipped, well-trained, and well-organised rebel group in Human space was capable of producing and equipping its membership with MJOLNIR-esque powered armour. They utilised UNSC surplus.

Not only is powered armour excessively expensive to produce (costing as much, individually, as a small naval ship), but it is incredibly complex and, in turn, difficult to maintain. Not only would one require extensive training in order to do so, one would also require specialised tools, equipment, and parts (which would also be prohibitively expensive), and a steady supply of them. It's also worth noting that UNSC powered armour would kill any non-augmented personnel that attempted to wear it.

(As a side note, fatigues are not armour: they're utilities, in the form of jackets and trousers)

I would simply recommend equipping your rebels with civilian-market protective equipment and UNSC surplus equipment, as well as civilian-market utilities.
