Placing field defences

[Dr.Zombie]

What are the rules for placing field defences?

Where on the table can you place them? Just in your deployment zone?

Bunkers and Trenches and such I gather can only be in you deployment zone as you would want your troops in them. But What about minefields and AT-ditches? They have very limited uses in your deployment zone. And would be better placed further out to deepen the defences.

Like so many things with CWC the answer is ... "it all depends!" 

If you are the Defender in a Scenario game, and that scenario lets you have field defenses, then you will be restricted to placing Field Defenses in your own deployment area or where the scenario states they can be placed.

If you are playing a more 'standard' Attack & Defense game, that is not based on any sort of historical OOB or actual maps, then I'd suggest that as the defender you should be limited to placing Field Defenses in the third of the table nearest you primary deployment area. The reason being that it is just not a particularly 'fun' game as the Attacker if the moment you deploy on table you have blunder straight into a load of hidden minefields. Also, that you (the Attacker) should have some room to manoeuvre and deploy on table.
Equally, most cold war historical Tactical Doctrines usually dictated that the Defending units start off deployed at a range whereby enemy units that do get disabled/suppressed by mines are actually in range of the defenders guns. So they can take advantage of disruption to the enemy formation.

Hopefully that is helpful?
