what exactly are you saying?
1. all that education and all that technology and the HUGE advantage of air and naval supremacy did not help in Vietnam or Korea
2. the Chinese gave the US a monumental ass whooping in Korea--not once, but twice--except for the Marines ..and this was 1950
..the Chinese are not stupid
.....MacArthur underestimated the Chinese right before they kicked our asses--twice--kicked a whole Corps off the peninsula--plus beating the crap out of the other units
Hold your horses there! The US in Vietnam had a very different problem...how to fight a war without the hope of winning...North Vietnam could not be invaded and that was the whole problem...
So, a bit unfair to say: well, they didn't win there, so their tactics, training and weaponry must have been crap...wasn't the case, quite the opposite...how many Viet Cong and NVA personal were killed?
and there lies a very good example for the point being made: while NVA and Viet cong lost a combined total of nearly 1 million men killed and 600 000 wounded, did the US lose only 58 000 dead and 300 000 wounded...the brunt of the casualties was taken by South Vietnam on the South's side with 300 000 killed and 1.1 million wounded...
Now, given the fact that the main fighting was carried out by the US military, it proofs exactly the point...bad leadership is a real problem in armies.
China used in Korea the only tactic, they have mastered: swarm tactics....if you call swarming an enemy position with your men and having them shot until your enemy runs out of amunition a good tactic than don't be surprised to get a strange look from people....but that is what the Chinese did...life is cheap in China....the total strengh of Chinese military personal was around 3 million and they lost roughly 750 000 killed and missing plus another 700 000 wounded
What was the outcome: an exhaustion peace...yeah, not so much of a victory after all, is it?
You can win wars with that tactic: Russia lost 13 million soldiers KIA in WW2....let that number sink in...but they sure weren't superior in their leadership on any level, having their greatest asset in the fact that they defended their home country
