re: US Army Chief of Staff: Army at high risk in war against China or Russia

It's more about the fact that we can't, and we never have, planned on matching Russia or China tank for tank, soldier for soldier. We have always developed offset strategies that help mitigate their numbers advantage.

The first offset was the nuclear capabilities and nuclear deterrence. The second offset was smart munitions. The third offset is what is being developed now, and it has more to do with human-machine interface, artificial intelligence, and machine learning. This will be crucial if we were to actually get drawn into war with Russia or China.

ETA - the third offset strategy will be expensive as f*ck to develop.
