Is there a way to express arguments for a use case?

I am currently developing a use case diagram for an army generation system in a game I’m developing. I have a process ‘GenerateArmy’ that requires a combination of troops and a supply limit that are retrieved from some other processes. Is there anyway to express this in the diagram to give it some more context? I can’t find such examples online so I assume i’m doing something wrong here…
