1.) In the Leader "Gun Tactics" family-less skill :
Improves the combat performance of this specific type of troops.
2.) In the terrain combat modifiers : "Guns" have maluses attacking in Mountains/Ruins, but Entrench and attack cross River/Escarpment/Glacier/Canyon like "Infantry".
So, are these both the same ?
Is 2.) for the Foot Movetype only : MachineGun // Bazooka + Manpad // Artillery + Anti-Tank Gun + Flak Gun ?
Is 1.) also for the Wheeled/Tracked "Guns" : Mechanized Artillery + Rocket / Missile / SAM / Atomic / ICBM Launchers and the Logistics moved Automated MachineGun / Turret ?
Something else ?
P.S.: What is this "Protector" TROOPTYPE, that seems to have -50% Attack and -25% defense in all Landscapes except Ruins ?
