Don't get me wrong, I think that heavy mobile forces have been very valid in WW2 - I just think that nowadays they don't make much sense anymore, and the main reason is a) today's intelligence capabilities that make everything big very hard to hide, b) air-to-air capabilities of big nations that are impossible to match for a country like Switzerland and c) the efficiency of air-to-ground bombing. Basically, you can have as many tanks and artillery defenses as you want, as long as you can't keep either air superiority or intelligence superiority, they're useless - and as far as I can tell, in both those areas you can forget holding up against a power like, say, Russia. On the other hand hundreds of thousands, up to 1M, resistance fighters in urban or woods territory with sufficient Demo, RPGs, good rifles and ammunition - it becomes a huge numbers game to fight this. The USA are basically the only nation that has become efficient at dealing with this sort of situation, and even then there's no end in sight in the Afghan conflict for example. That's why I think a guerilla army that has been trained at this, for everyone to see, is a much bigger deterrent than heavy machinery - and it also takes much longer to be outdated.
