Infinite Care Package Glitch

This glitch allows you have infinite amount of care packages. To do this you have to at least get 4 kills or 3 if you have hardline on. once you have a care package pull it out but DO NOT THROW it. walk to a surface were you can climb over. Then press A and while climbing press right on the D-pad twice and if done currectly you should still be holding the care package. then throw it and retrive your care package then call it in. if its a ammo crate you may have to die before you get another. REMEMBER you have to jump over and hit twice on the D-pad each time you get a new care package.
