When I first used the smoke nade launcher I thought, this is pants... but, it's ideal use, according to the read-up, is to identify enemy positions.
However... through the week I used it on tanks and it worked a treat... the driver can't see RPG positions, nor can he see a recon sneaking up on him. If you see it done on any servers... a member of GSV did it first.
Also, if you are taking an exposed position, have an Assault trooper with you to repeatedly smoke out your position at the flag. Be careful if you have trouble with a low spec video card though, as I fired off one too many smoke nades and lagged my self into disconnection from the server... got the flag first though...
Also, I suppose over use of this tactic amounts to grenade spamming... maybe...
