Traditionally, units can only hit one unit at a time unless the weapon has an AOE stat. Only a few AOE weapons can hit an auto-spread group, in the category of aircraft, AA, or artillery. That being said, you might have to manual micro to avoid HE or CLUS on your ground vehicles.

Accuracy is how accurate the unit is at the weapon's MAXIMUM range IIRC. Accuracy increases as the units are closer together.
