After a great deal of deliberation on this matter, I will briefly enter this conversation.
A tremendous amount was learned in WW2 and many of the lessons learned still apply.
1: Have a clearly defined goal; WIN.
2: Be allowed to achieve that goal.
3: Do not attempt to initiate with out more than adequate resources of your own.

First, identify your strategic targets, and eliminate them, completely. This goal is to deny resources and communication lines of the enemy.
Recon must be maintained at all times. Much easier to attain now than in WW2.
Identify your first two tactical goals. At least two, in order to follow up reduced ground assets, which were sent to Goal 1 by Goal 2.
Close order air power is now essential, as was so valuably learned in WW2.
Ground troops are then sent in to Goal 1, with unfailing close air support.
When it is likely Goal 1 will be obtained, send the following ground and air support to Goal 2, and follow up on obtained objectives at Goal 1. Repeat.
Do NOT give up objectives achieved.
Through out the campaign, do NOT loose sight of the objective, WIN.
Continue as necessary until goal has been achieved.

Obviously this is all an over simplification, but it must never be forgotten why you are there; TO WIN. Unless that is quite clear, then it should not be attempted.
