2PReDS: I only partially agree with you: units in a trench do NOT receive any penalty to defense against ranged towers, but you are right about the -3 penalty for units in a trench when attacked by other units. From a gameplay perspective, it's more accurate to say that the attacking unit receives a +3 bonus to attack when attacking a unit standing in a trench :)
