Fixed core unit changes in User Campaign

[Brian61]

Finally getting back to reworking the Black Brigade campaign and I need to know what happens when you change a unit's weapons, ammo, and/or number of men in a fixed core unit.

The example I'm looking at here is changing a 10 man unit with a rifle grenade in slot #2 having 10 HE ammo into a 9 man unit with a LMG in slot #2 having 80 HE ammo.

Do the weapon changes persist throughout the campaign?
Will the unit start with 10 or 80 HE ammo in the later battles?
When the unit is repaired, will it have 9 or 10 men?

Thanks,
Brian
