I respectfully disagree.

The vast majority of our military stuff is NOT shielded/hardened. We have consistently been unwilling to foot the the bill in our pursuit for the biggest bang for the buck. This typically means off-the shelf technology.
Not denying some is, but the vast majority is not.

Soviets have taken a different approach for decades!!! (See above) Don't know about Chinese, but I would be surprised if they didn't follow Soviet/Russian lead.

Thanks for the info DK. I wasn't aware that we lagged behind others in this area. Not a welcome surprise.
