Points for Assault battle ?

[Imp]

The flags could represent several things but generaly areas that must be held to continue your assault or to stop the enemy from breaking into your rear area, they are not the rear area but routes to it. Gave my example as easy to explain, they are letting them have them because it is essentially a trap & they expect the enemy to take this rout, in game terms the flags.
Another explanation
The armoured force is in a position to protect the flags (general area)but safe from arty concealed. Once a force worth commiting for is present the FOO who has been watching & has area pre plotted calls in the strike & tanks counter attack.
If did deep defend the flags would still represent routes to rear just off the scale of the map they would not let them get far enough back to threaten support in important rear area unless of course it all went wrong.

The diffrence in our point of view is you think armour should be static where as I believe if possible it was used as a roving force to counterattack.
We shall agree to differ in our beliefs.
