I'd say, in the short run, you would lose money because I doubt you would kill the # of people needed to repay the cost of repels. In the long run, especially if you killed all the lancs doing it, you may end up getting the flags and scoring a lot of money. Edit: Maybe if you had bounty, it might repay it but it's a suicide mission and you would lose your bounty, which I don't think you would want to do.
