Does anyone have a good explample of an MP Company Commander's intent or mission statement I could work off?

You should receive a Commander's Intent and Mission Statement from your BN CDR, usually in the form of a Yearly Training Guidance OPORD or IDT FRAGO. Yours should nest within his/hers. As a Company Commander I wrote a monthly IDT OPORD where I published my intent and mission but there are other ways to accomplish this. Some units use "Drill Letters" or CONOPs as well. What did your predecessor use? Surely there are some legacy products and orders in existence that would have mission and intent statements.

Your Commander's Intent is probably going to change month to month, or at least on a quarterly basis. After giving this some more thought, are you possibly looking for something more along the lines of a Command Philosophy?

CPT (Join to see), I'll check with my good friend MAJ Ben Ruff. Do you have a deadline for this?
