The Issue of munitions assigned to troops on defense is one I have been interested in. CS answered the question of healing as follows:
”Hello Jolly,
We are so sorry that it took so long so that we can provide you with the details regarding your question. The Braced Plating Munition can only be applied to the troops, right? If you outfitted the Braced Plating into a troop type that was donated to your village and you have the Angkor Wat wonder placed in your village, then the healing effect of Angkor Wat is boosted for that donated troop type. However, here's the twist, the healing effect is not applied to the defender troops that are spawned from your buildings. They will still receive the Angkor Wat's healing effect but there will be no bonus from the Braced Plating's Healing Received effect.
For example, you outfitted the Braced Plating on your Heavy Tank. Now, your allies donated some Heavy Tanks and you set the toggle on for donated troops to defend your village. When you are attacked, the Angkor Wat's healing effect will be boosted by the Braced Plating when healing the donated Heavy Tanks. However, the wonder's healing effect will not be boosted when healing the Heavy Tanks that are spawned from your Bunkers.
As for your mention that the instant retrain is not working, can you specify what happened when you try to instantly retrain your troops? Did you receive any error message?
Hope this answers your question and we'll wait for your response regarding the instant retrain issue you experienced.
Kindest Regards,”
I then asked whether other lines in other munitions that appear to be useless for defenders are really useless for defenders. Today they confirmed that they are. I had giventhem the following example:
”Another example: “-5% Damage Taken from Defensive Buildings” or “+15% Assault Rally Effect” which are the first and tenth lines respectively of Communications Relay. Spawned defensive troops are not damaged by defensive buildings and an Assault Rally cannot be used on defense. Please confirm that those lines have no benefit if the munition is assigned to a troop type spawned in defense.”
So the takeaway from all this is that, depending on which they are, munitions assigned to troops spawned on defense will not be as strong as if applied to the same troops when used for attack.
