I saw that running around behind the enemy team in Rush is frowned upon.

Apparently an M60 with extended mags set up on a railway carriage ,behind the hill on Noshir canals (second MCOM), does wonders to make the other team "think about what they're doing" whilst camping on the hill.
Don't all stand so close together next time, and don't land a helicopter there!
Oopps! my bad.
