In this history, the army finds out a way of making reliable exosuits, but they can only help its user to carry more weight while walking and running, it can't throw cars, jump over buildings or anything that is super duper cool.
The thing is that I started thinking a lot about the structural design of the bulletproof armour that these soldiers are meant to carry, specially for the ones that ignore the military rules for amount of armour (because you can't be transported if you weight more than the vehicle) and try to be impenetrable fortresses, even if it means weighting half a ton. Simply put, they just don't want to die.
And even though I put a lot of thought on the structural design of the ballistic armour and its various layers, wouldn't it be simpler, cost-effective and easier to just fill bags with sand (sandwiched or not between plates of metal to increase its protection) instead of armour?
After all, it is what most soldiers do all day during war: dig holes, fill bags with the sand/dirty of the holes and pill the bags. A sand bag would be easier to replace than a goddamn ceramic vest with 10 layers, and soldiers could just empty them before getting in the choppers and escape punishment by their superiors (and be more vulnerable while transporting).
And the last detail is that, during a full scale war, the soldiers don't need body armour, because most of the causalities would be caused by weaponry so powerful that can easily erase buildings (like artillery bombardment). Maybe a half ton of ballistic/sandbag armour could help you, but if I knew the answer to that I wouldn't be asking here.
What would be better? Half a ton of Sand (and metal plates) or half a ton of ballistic plates?
