The red flag can be deployed the same way as any troop. It will not do anything, and defenses will ignore it. It will act as an obstacle, it will cost 10k gold to remove.
The purpose is the red flag is for players to "flag" TH trappers and other raiders will be prepared for teslas, or to "flag" a base asking for the guy who is nexting to bash the base.
