How to explain this problem ???

andSupport units that are directly attached to combat units will automatically be added to the battle.
Support units attached to headquarters units must pass a series of checks in order to be committed to a battle. (...) The maximum number of attached support units that can be commitment by headquarters units to a single battle is 6, with the exception where the defending combat units are in a light urban or heavy urban hex, where the maximum is 18.

There is a maximum number of SUs that can be committed by a single HQ per combat but I am too lazy to look it up right now.
However the really significant point is that the commitment of SUs requires die rolls based upon the attributes of the HQ leader controlling the SUs. There have been threads detailing investigations into which attributes but I can't find them anymore. All I remember is that the process is similar to but still different from reserve activation
Die rolls everywhere affect everything is the answer to most questions about this game[:D]

15.4 in the manual clearly states that:andSupport units that are directly attached to combat units will automatically be added to the battle.Support units attached to headquarters units must pass a series of checks in order to be committed to a battle. (...)

There should be no limit on SUs attached to CUs and they all should take part in battle. Perhaps it's only display issue?
New Rule- Added a fire penalty in combat when there is a large number of attacking units. The force value of the attacking side is calculated using the following values for each non-support, non-artillery division unit attacking:
Corps 15
Division 9
Brigade 5 (unless the brigade has less than 2000 men in which case it is 3)
Regiment 3
Once the force value exceeds 28 there is a chance that elements will not get to fire during combat. Artillery elements are much less effected (only impacted at closer ranges in combat), and the chance that elements will not fire increases as the force value increases. In general though, adding more units should result in more elements firing, but a lower percentage of the total elements will generally be firing as the force increases. The CV values of the attacking units are not changed by this rule.

Without a clear answer I decide to continue my turn and other battles to do some test.
The first thing I decide : not to engage my art division in my combats but do 1 or 2 bombardement with them before the ground engagement. I had the impression that my problems begins when I started to use them.
After 4 battles I came to the conclusion that everything works perfectly up to 6 Corps are involved in the combat but if the number of Corps increases, the number of SU (even directly attached on units) engaged declines.
I have the feeling that the size of the units is also important.
It's just my first conclusions and I will keep an eye on my future combat reports.
Sorry for my poor english [&o]

That's a nerf that was put into game a long while back.
If you have X divisons or Corp in a single battle elements involved in battle will decline.
The more units the less elements commit to the battle.
Not going to bother to find it some other nerd can.
I didn't check this number, its a good idea thxORIGINAL: morvael
All SUs attached to CUs should be included automatically, without limits. I wonder if perhaps you have reached hard limit of units involved in one battle. Your problem starts as you reach 28-30 units, both on and off map.

Morale farming? The proper execution of which would be a welcome thread of its own...

By the way, why do you need such overkill? What is that you have to defeat, that you need 2000+ CV? In my battles I usually attack with 2 corps + div + reserves, sometimes with a Tank Army (3 corps) or two armies at most (4/5 corps + div), 1200 CV at most. Thanks to raw elements number advantage you should win on 1:1 to 1.5:1 80% of the time (depends how many reserves kick in).
