Question about the armorer's leader skill

Having been forced to develop the mandalorian faction for galactic challenges I've been running the armorer as the leader. Now I understand that parts of the lead skill are only temporary lasting for 2 turns I believe but what about the 200% protection (or health?) increase? Is that also just temporary? I havent tested it out much since I dont bother to clear too much of the gc to see if the increased stat remains intact past 2 turns as my squad can usually clear the battles by the second turn.
