Me giving just about my EIGHTEENTH combat order of the POI (period of instruction) at MOUT town!
You and the Combat Order will become very familiar at TBS. In fact, you'll probably write over 30 combat orders in your 6 MISERABLE MONTHS in Quantico. Haha. All grouchiness aside, here is a really helpful Combat Orders Checklist
that was passed down to me before I headed to the BOC (Basic Officer's Course). Use it to double-check that you've got everything you need . . . especially if you're the Marine holding the primary billet.
Note: If you print this double-sided, you can laminate it and bring it to the field with you! But soon enough, you won't need to because you'll have this stuff memorized.
