re: scenario design

[Gordons HQ]

Hi Peter, as stated by others here it depended what you had available to defend with. I've read of single under strength companies having to defend miles of front line, I'm not sure quite how they did that.
However the following is from David Glantz's book on the battle of Kursk and it deals with the Russian defence. I think you could perhaps take this as a benchmark for a good defence and then adjust your hypothetical scenario as you think fit.
Anyway if it helps he states re the Southern Sector:-
The 37 rifle divisions manning the first defensive belt formed 350 battalion defensive regions, of which two or three arrayed in single or double echelon formed a regimental defensive sector 4 to 6 kilometers wide and 3 to 4 kilometers deep. Divisional defensive sectors averaged a width of 14 kms (from 6 to 12kms in especially threatened sectors) and a depth of 5 to 6kms.

So from this I think it is possible you could hopefully work out a rule of thumb for any unit in good defensive positions and moderate it occordingly for poor a defensive position.
Of course any other support that was available would also be arrayed amongst these battalions.
I hope that helps.

Gordon
