The Elite Mercenary doubles your payout at the end of a Co-Op Sortie. If you were going to get 1500 credits, you'll get 3000. 5000 would become 10,000. I would suggest people wait until they are acclimated to the game before using one as the bonuses will be greater the better you preform. Try to stick to the Co-Op missions you're most familiar with/best at while the contract is active. Also, PvP Death Matches pay out way better for me, so I'd suggest you use a contract when they are available to play.

The Plant Investment seems to be a little more tricky. The parts and aircraft the research is preformed on after a sortie are still random. For me at least, it seems like sometimes I receive some research on a number of different parts and aircraft. Other times only a few items receive research, but the level increases a lot more than usual.

Since it is a pay to play game, I would suggest stocking up gifted or purchased fuel, and then activating one of each of the contracts at the same time. Then use the stock piled fuel. That way you'll get the most bang for the buck.
