last time they interview russian military analyst. they said that in their war games, russians always won every fight. while for nato and US war games, sometimes the home team will lose. then when actual combat situation the nato and US ones actually perform better due to realistic simulation and the lessons learnt.

improvements in their smart bombs and stealth came out directly from the lessons learnt from their losses in the air battles of vietnam.

north vietnamese and VC eventually got airforce, sams and artillery/rocket launchers. what knife and spear.
