Countermeasures how do you make it so they stay on so you can do multiple

I need to make my counter measures stay on but I don’t know how

Are you talking about having it so that you press a button and it shots out flares/chaff every second or so?

Bind a key to the countermeasure series. After that, you can also set how many come out and how often in the pre-spawn screen.

Thank you very much I greatly appreciate your reply but I figured it out thank you
