? on Fulda Gap '85 and other HPS games

A few additional N44 related questions:

1) On several occasions I have had the divisional 4.2" mortar battalion of Commonwealth infantry divisions refuse an indirect fire order, even though the unit it is supporting is a battalion from the same division, within range of the target, and under command.

The error message I get is something along the lines of 'can only support units subordinate to that unit'. My understanding is these were divisional assets that could support any unit of that division, much like the heavier field artillery. Any idea of why this is?

2) How does one utilize the Aster artillery observation planes?

3) related to #2: How does one utilize the recon air assets? I notice a few units display attack values. Are theses intended to represent armed recon? If so, how do you get it to attack a target?

Thanks in advance
