M320 grenade launcher ammo types

If you are wondering how to use smoke grenades with your freshly unlocked M320 grenade launcher: you have to unlock the ammo first. It doesn't seem to be documented in Battlelog, but after 10 kills you get flechette rounds, smoke rounds follow at 20.

Support players can switch around the ammo on their mortar directly, using 1 for the normal shells and 2 for smoke.

Smoke can be a huge asset to cover assaults on an MCOM, especially in Rush games. (Seine crossing bridges say hello) Happy hunting!

Battlefield 3 default key bindings

Since it seems unusually hard to find/google the default keybindings for the new Battlefield 3 title that I've been playing the last couple of days, I've decided to quickly make my own list, shared here for your convenience. I'll expand and update over the next couple of days.
