FOO class has communications speed benefits to the artillery units, that simply ramming the artillery command rating up on a regular leader will not get you. Though it may well help.

Also - in a campaign, as you call in arty, your arty skill will tend to rise, so core force scout helos (or any other 0 unit) if used to call fires a lot, will tend to get better at it as the campaign progresses. Will still have an 0.2 delay though to adjust fire as not a trained FOO.
