This war game has been discussed many times.

One thing to consider is that Van Riper summoned assets unrealistically he used small boats to avoid detection but then attributed load outs that they couldn't realistically carry.

He also moved information unrealistically assuming that his units could communicate as efficently with paper moved by hand as they could with radios.

There are real, valid criticisms of the lessons we should have learned from the exercise, but it's not as simple as most analyses make it out to be.
