Combat Tactics and Strategies

[ChalkLine]

I'm in a PbP game, and in every situation where the PCs have stood their ground and fought, they've been slaughtered.

True, the PCs are all fairly unskilled and are fighting a crack team of VDV and Spetsnaz (thanks GM! ) but the defining feature seems to be that if the PCs stand still they get creamed.

So I've read up on infantry tactics, and the German concept of 'elastic defence'. This is where you start with strongpoints that shelter you from bombardment, and fall back with supporting fires to trade ground for time to counter attack when the enemy seems disorganised in the assault phase.

How realistic does the forum see this?
Do strongpoints represent tactical assets to fought from and defended?
