I don't actually recommend using this unless you're playing offline and just want to experiment. You will be labeled a cheater for using too many deployables.
This is really just a proof of concept I guess.
Allows you to interact with inactive ECMs to pick them back up. Only your first two ECMs will function and after that they'll be inactive and have the feedback timer reset. They will recharge their feedback ability after 4 minutes if you have the appropriate skill.
