I did this challenge in the past, and works fine for me.
Wait 2 care package (Orange one, not blue), make sure you're the first one to open (not team mate or enemy or already open), take some/all item on both of care packages.
You have to repeat this challenge in 2 games.
I believe I take some items should do it, but to be sure (in case there is bug), try to take all 3 items, then drop it if you don't want it.
