Why do some of my armour units become unavailable?. It says "not enough command points" when I have ample points to deploy them?

Is this a glitch or an unexplained feature of the game?

Anybody?

Note that command points are not the same as resource points (the 'money' of the game).

From the manual:
The amount of available Command Points (CP) is displayed in the top-right corner of the main UI bar, next to the resources display. These values determine how many units can be deployed at a given time in the current scenario.
There are 3 types of CP, one for each of the three unit categories available in the game:
- Land CP, indicated by a green helmet icon
- Naval CP, indicated by a blue anchor icon
- Air CP, indicated by a red aircraft icon
Each unit type consumes a specific amount of CP when it is deployed. If there are not enough remaining CP the unit cannot be deployed until more CP become available through a specific scenario event or the destruction of another Core unit. Auxiliary units do not consume CP and do not return their CP cost to the reserve pool upon destruction.
