Pokemon Conquest

I'm in the MQ and have 7 castles. I need to get some fighting pokemon and I have a few warriors who are good with them, but they have other types now. I need to move them to Pugilis but I can't since all my castles are currently full.

So I want to delete a few warriors to make room to move some around, but I can't figure out how to do it.

So how do you dismiss a warrior?

Thanks.

I'm glad your opinion differs from mine. What a boring place this world would be if it didn't.

1.) Recruit a new warrior with a fighting type, put him into a nation with 6 warriors, then you can dismiss one you don't want. This will probably be the best thing you can do given your circumstances.
2.) Do not delegate, mine, shop, etc. with any of your troops you want to get rid of for about a year or two, and they will leave. The issue with this is that your opponents will get stronger during this time, and thus you may find it very hard to fight that battle you can't beat even with all fighting types.
In my opinion, try to link with as many fighting types as possible, you should only need 6 max, and then fight at that point, just make sure they are all decent level, in the MQ you should use one powerhouse team to level them up and make them take out whatever stands in your way... although you may need to find one replacement for your warlord/Oichi.

3 Pick a kingdom you have with 6 warriors in it and at least 1 you would like to get rid of. Enter that kingdom and personally make then mine develop an area or train. after they have become gray from using their turn. Leave the kingdom and go to another kingdom that has someone you want to keep. Transfer them to the kingdom that you had just used and select the warrior that is gray and it will prompt you that since the warrior has already used it's turn doing this will dismiss that warrior. Tell the game yes and presto. You lose 1 warrior or warlord and have 1 open spot. you can do this as many times as you want till you have 1 kingdom of 6 warriors/warlords if you really get board but i doubt you'll need to free up that much space.
