	If the element is ordered to hold action, it will remain available for selection to support a later element's attack. It may not, however, choose to lead an attack after its own initiative interval has passed.

It may counter-attack, as decided upon immediately following an attack's resolution, however.

	Up to four elements may attack the same opposing ground element. The actual ground combat may only occur once all involved elements have been assigned this round's orders.

	The second step is to process the ground attacks, which are resolved by rolling the attacking element’s D Factor and adding its Attack value; the defender then rolls its own D Factor and adds it to its Defense Value. The defending element takes 1 Attrition damage per point that the attacker’s total exceeds the defender’s own. If more than one ground element is attacking the same target, the attackers gain +1 Attack per additional attacker. Because of the nature of this opposed roll, it’s typically most efficient to use multiple elements to attack a single opposing element rather than have them attack individually.

	As one single attack is simply the attacker rolling for the value of its strike and the defender rolling to defend against it, the attacker is free from any threat of return damage via these procedures. In-character, if the defending element was not yet already assigned to lead or support an attack against that original attacker, it most likely was itself attacked while involved with its separate orders (possibly as a flanking maneuver or diversionary attempt). The defending side may choose to re-target or re-assign elements to counter-attack the original attacker, but no element may engage in more than one combat scenario per round.
