I've started a PSN profile where I keep Care Package, Sentry Gun and Emergency Airdrop selected at all times. I play normally, but whenever I get a killstreak, I just throw the flare on the ground and let the quickest person get to it. I try and defend any crates I get so that my team collects them. I never collect them myself.
My PSN name is FreeCratesOnMW2, so if anyone wants to add me and join games that I or other members are playing, you stand a good chance of getting a lot of share packages!
FAD! now has 4 members - 3 on PS3 and one on PC. We're looking to get at least 1 XBOX player this week.
If anyone wants to join me in this, then again add me on PSN. The Clantag is [FAD!] and if you have them, use the Title "Share Package" and the emblem for getting 50 Care Packages (spinning, yellow box and parachute). You'll need CP, Sentry and Emerg. Drop selected at all times. Also, keep a tally of how many you give away of each (so don't count those that land outside the map. Still count ones that enemies take though), so I can have a counter of how many crates FCP! donate overall. I'll keep this updated in a Steam group. It'll say something like - "To date, we have donated: 36 Care Packages, 29 Sentry Guns and 8 Emergency Airdrops!"
The Steam group is up, and called Free Air Drops, http://steamcommunity.com/groups/freeairdrops
