FEBA, I didn't realise you did a c&p. I certainly didn't say anything about the spams. Joffre was French.
I think the Americans have been suffering ever since the Civil War where they were horrified by warfare and the casulaties. Ever after I believe that have tried to minimise casualties by use of technology. In WW1 they helped . In WW2 they helped. True, once the Japanese had attacked things changed but they still brought technology to play.
In the 60-73 war they used all sorts of technology to try and get the war winning weapon.
In GW1 and GW2 they had it hacked.
Next, personal reactive armour?
