Supply & action points

[MTTODD]

Firstly sorry if this question is a bit basic.

But I have units that are in supply(green dot) which sometimes have less than 100 action points and
units out of supply(red dot) which sometimes have 100 points.

What is the relationship between supply & actions points ?

And what does supply actually give to the unit ?

Many thanks for any help.

Supply is not the only thing that can lower your AP. Poor command and control for example can lower your available AP (mostly in the case yellow scenario for the allies).

Units out of supply with 100 AP just got out of supply, if they stay out of supply for several turns in a row their APs per turn will go down and ultimately get to 0 within 3 or 4 turns if I recall correctly.

Thanks for your help.

That explains why sometimes I see units with a red dot which have 100 AP.
