Prison, Buildings Mobile Strike.

Prison.
 
Prison in Mobile Strike is the building that allows us to retain enemy commanders if we captured after an attack.
We can only retain the commanders who have a headquarters or above level 10.

If we enter the prison commanders we can see that we have captured and the time remaining to be released.

If while we have a Commander captured the base attack us and we suffer a defeat our captured Commander may leak and lose major points that we would receive.

  If we have a commander detained in our prison will see a logo above it indicating that we have a commander withheld.
