I don't know if it should be totally written off as "fighting the last war", since as a defensive-style armed force (ie, we don't invade to expand an empire like the Commie's did/do, aggressors can pick their war spot and develop for that), you can't always predict where and what the next war will be, so can't exactly develop a weapon for it with complete foresight.

LOL. Switzerland has a defensive-style armed force. The US has an offensive/expeditionary-type force

The US military has not had to defend this country against an invading army for more than two centuries.

We are not defenders. We are invaders. The United States was built via invasion, aggression, and conquest.

We have attacked and invaded countries all around the world. From the jungles of Cambodia, to the deserts of Iraq, and the mountains of Afghanistan.

That's why we can't develop a weapon with complete foresight. We don't know what type of terrain and climate the troops will be ordered to fight in next.
