Fuchs has some very solid ideas and some I consider worth listening too. I would never dismiss any of his points out of hand, but...

What everyone seems to be missing is that this is not merely an issue of minor tactics. There is a lot of very small amounts of information about this type of thing, because no one views it as an Operational Concept.
This is not about Platoons, it is about Formations, Fronts and theatres.

It is not about gallant little teams bouncing about the woods with sacks full of RPGs. It is about a Formation and above defensive operation, that trades depth for attrition. It is the reverse of deep battle.

So if you want to do it in Estonia, the aim is not to stop the Russians, but to make sure only 1 serviceable Russian tank ever gets to see the Baltic Sea.
