How can we mark anti-air only units?

[slogic]

I'm thinking about the way how we can mark unit is an anti-air only unit. These units should not be considered by surface threatmap data. The only nice way i see to distinguish anti-air units from anti-air + ground is by additional military group tags like: SNIPER, ASSAULT, ARTILLERY. If they exists along with ANTIAIR tag then unit is not anti-air only. For mobile units is could be ok, but what about STATIC units (buildings)?

For static buildings i'm currently assuming DEFENSE tag means unit can shoot ground.

I really need help on this. Also i need 100% method to detect such units. Looks like until http://springrts.com/phpbb/viewtopic.php?f=15&t=22988 is fixed i can't do it fully automatically.

I have a fresh idea. DEFENSE tag will be removed. STATIC & <any_military_tag> automatically means a building is some sort of defense.

Damn, in NOTA mobile defense is introduced!

Resolution: all defenses which should be built in special spots (to cover static units) must have DEFENSE tag. Combination of DEFENSE + any of SNIPER, ASSAULT, ARTILLERY,PARALYZER tags means unit can shoot ground. DEFENSE + ANTIAIR means unit shoots air only. Defense can be both anti-ground & anti-air but it can't be assigned to both coverage layers (architectural restriction): any defense with ANTIAIR tag will never be assigned to anti-ground layer.
