Editing VB-Ground Combat (section)

===Combat===
Any race with GCU on a planet can choose to attack ground units or PDCs of another race on the same planet. Note that attacking and defending are two different actions so the attacked race may decide to remain on the defensive and not counter-attack. If both sides attack each other, two separate combats are calculated. As the combat is potentially covering the entire planet, ''' each combat round takes place during the five day increment''' . If time is advanced by more than five days, one combat round takes place for every five days in the increment.

====Vs. PDCs====
Attacking ground forces will have the option to concentrate their efforts on a specific PDC (based on sensor contacts) or fight a general action against enemy ground forces outside PDCs (if there are any). This is accomplished by choosing which PDC or Population to attack on the Ground Units tab of the Economics window. If a PDC is under attack, only the defenders of that specific PDC are able to take part in the defensive battle. However, troops can emerge from other PDCs to fight an offensive action against the attackers in the field and try to destroy them. Obviously this won't be a good idea if there are enemy spacecraft within weapon range. If the attackers are concentrating on a specific PDC, the defenders are able to move around between other PDCs but are not able to reinforce a PDC under attack. In addition, the PDC under attack may not reload its magazines from the planetary stockpile.

If a PDC is captured (i.e. all ground forces within it are eliminated), it becomes part of the attacking player?s forces. He can move troops in to garrison it and the defenders may try to recapture it. There may be a chance the defender will attempt to blow up the PDC or damage its systems before it is captured, depending on his racial characteristics.

Note that [[Ground forces|Combat Engineers]] get a 100% attack and defend bonus in combat vs. PDCs.
