Pretty much everything the military uses has a measure of EMP shielding. We've know about it's effects for over 50 years now. Signal jamming is an obvious weak point - one that disappears as autonomy is increased. Distributed control would reduce this issue, (as in, have a single soldier/operator manage 10-15 units). Eventually, you remove human control entirely, and along with it, this issue.
