It seems like defence planners are forever trying to construct weapons systems that are economical (usually meaning light and mobile - and cheap) rather than systems that are rugged and can survive battlefield threats (usually meaning heavy and slow - and expensive).
You'll notice that the soldiers manning the systems will hang all manner of personal gear like duffel bags or add sandbags or anything else that might improve a vehicles chances of taking a hit. They don't seem bothered by the fact that it slows them down or uses more fuel.
I think the Stryker is an example of a system that budget minded planners love but soldiers given a choice would opt out of. They'd rather use something like the Israeli Azcharit or Namera, the Jordanian Temsah, or some other very very heavy APC that puts more armour between their person and all the bad stuff going on outside the vehicle.
The US isn't alone in the move to wheeled vehicles - the Europeans are doing the same thing. But the Russians, Israelis, and others seem headed in the other direction (the Russians have the BTR-T which is a converted T-55 hull and some other unit which is a converted T-72 whose name I don't recall). The Ukrainians have a couple of "stretch" tanks that carry infantry.
Is the Stryker just like the Sherman tank of WW2? Kinda fun to drive. Mechanically sound. But in battle, when the fit hits the shan, you'd rather be using something substantially more durable?
