The downside to these high tech armored soldiers is that, like the knights of the Middle Ages, they cannot be challenged by civilians armed with readily available weapons. A group of citizens armed even with military small arms like the AR-15 or the AK-47, would be no more able to stop such a force than medieval serfs would have been against mounted, armored knights.

What brought down the autocratic, feudal systems of the Middle Ages was the development of the firearm. The collapse of feudalism set the stage for the development of capitalism and the rise of representative government. The authors of the Second Amendment understood the importance of an armed populace. (The militia referred to in the amendment consisted of all able bodied males between certain ages.) The ability of the citizenry to overthrow a tyrant is the final safeguard against tyranny.

On the plus side, we're busy fighting a war against "civilians armed with readily available weapons".
