Parent and children action inheritance

I have a parent / children relationship table where the children have an action but given the fact that there could be up to ten children we want to allow a way to set the action from the parent level that propagates to children.

The parent itself does not have an action. The issue is that you can set the level from parent but you can also go at one children and change that and this is where I am looking for some help in how to portray that. Sketch to make everything clearer:

Step 1 - Everything is disabled. Step 2 - Turn the level to high to all of them. Step 3 Change the level to some of the soldiers.

Question: How should the Parent look after changing childrens values ? ( Note: Parent itself does not have a level but controls the level of childrens to allow bulk manipulation of childrens )
