Unlimited Medipack

When you encounter German fortifications with Medipacks scattered on the ground or on tables, get that Medipack, do what you have to do to use it (it will be the last pack in your inventory), and look towards the exact position of the Medipack you just used. You will not see another Medipack there, but if you use your "Pick Up" command (Right Mouse Button is default), you will pick up another Medipack, and you can repeat. You can do this indefinitely, as long as you have used the previous pack. It is possible to heal your entire squad using one Medipack from your inventory. Also, you can drop Medipacks, pick them up, and use this same strategy.
