unfortunately this is not possible without modding, there is a code in a file called protox, GivesLOSToAll, and is attached to this unit. you can remove this through some simple editing but if you want to publish the scenario you would need to include the edited file. in my experience people who play scenarios don't like extra files, so if you can find a workaround that's suitable like using a different unit or changing the gameplay of the scenario, that might be best.
