How does Cover work?

[RubberNeck]

Cover seems to be diminished by firing from different angles. The source code wizards would have to address this more specifically, but I make it a practice to engage enemy infantry with multiple units whenever possible. Assume my unit X fires on enemy unit and draws return fire. My follow-up shot is from my unit Y which is ideally not in the same hex as X. When enemy unit returns fire on unit Y, it is then engaged by either unit X again, or better still by unit Z in another hex. Casualties are invariably higher for the enemy unit when done this way than by shooting 4 or 5 rounds from X, then 4 or 5 from Y and so on.

This may also be because suppression is lessened by spreading it over multiple units which allows for greater firing accuracy.
