For turrets, I would just use normal rules thoughout, so Rallying will be affected by being 'Broken' (lost comms) and proximity to enemy (jamming, smoke grenades or just plain old shooting)
===================================
Markerlight and Guided missiles with target in partial cover is messy as currently written. Firstly, while E:A shooting is done on a weapon by weapon basis, the choice of shooting at a formation partially in cover is made by the type of weapon fire.
Quote: ( From the SG FAQ @ , )
Q: if someone shoots at my tactical formation, which has three exposed rhinos and six marines in cover, does the attacker have to take the -1 to hit the rhinos (which is AT fire), if he wants the tactical marines to be potential targets for his AP fire?
A: The choice to shoot at in-cover or out-of-cover targets must be done by the entire formation. It can only be separated by type of weapon fire.
If you had AT, AP, and MW fire in one salvo, you could fire AT at out-of-cover, AP at in-cover and MW at in-cover. Or any other arrangement, as long as all of each fire type (AP, AT, MW) is directed solely at one target type (in-cover or out-of-cover).
You cannot split up targetting of a single type of fire. If an IG infantry company had 2 units out of cover and 10 units in cover and you were firing with, say, 8 AP shots, you could not target 4 AP at out-of-cover and 4 at in-cover. All the AP shots would have to be directed at a single target type.
So, it would seem appropriate to treat Markerlight in the same way as cover, requiring the entire formation to shoot a class of weapons at markerlit target (with bonus where appropriate) or at the enemy formation in general (without the bonus).
However as Neal said earlier, this still gets messy when you consider the larger Tau vehicles firing at a Markerlit formation that is also partially in cover as you get up to four variations:-
- Target in the open
- Target Markerlit in the open (+1 bonus for some weapons, +0 for others)
- Target in cover (-1 bonus)
- target Markerlit in cover (-1 for some weapons, +0 for others)
This seems to be inviting issues, so what should be done to simplify this? For example, could we alter the weapon stats to assume the ML bonus is added, but prevent the GMs from firing unless the target is Markerlit.
