One of the things currently existing in MC system is that the core forces ("your" units) are always occupying the same spot in the game.
For example, in MCNA, core forces are formations A-H. They are always A-H.
Now in smaller scenarios, part of your core force may not be present, but the absent units are not replaced. That is, their formation slot is not filled in by other units.
Knowing that (which I think is mentioned in the introductory text of the campaign, and I quote:
"YOUR CORE FORCE
"Your base or core force will appear to one degree or another in every confrontation. On occasion for the smaller battles the entire core force may not be used.
"They are formations A through H. There may be more units in the battle, but your own personal force will follow you through the hard months of action in North Africa. You will have at your command the following units.
"A Formation - HQ Unit
B Formation - A platoon of Mechanized Panzergrenadiers
C Formation - A Platoon of SdKfz 222 Armored Cars
D-G Formations - A company of MkIIIe Medium Panzers
H Formation - A Platoon of MkIVd tanks"
With that information, you already know which ones are your core forces. If there is no formation E, then you know a platoon of MkIII tanks is not present for that battle.
I hope this helps to focus on the core force.
