battlefield-3
I've been trying to get a marksman award with the shotgun just for the pure "wtf" credit. So far I'm using frag rounds with the Saige 12K and a 7X scope.
Is it even possible though to get a marksman award with something that isn't a sniper rifle? I can get headshots with the shotgun, but it's extremely difficult getting 1 shot kills with headshot and a shotgun
I cannot find a definitive source for this, but apparently:
40mm flechette rounds are unlocked after ten 40mm grenade launcher kills
40mm smoke rounds are unlocked after twenty 40mm grenade launcher kills
Why this can't be displayed in the battlelog in some form along with all the other zillions of weapons unlocks, I have no idea. But this is what people reported from the beta.
edit: confirmed, by me personally getting the unlocks. I presume the same rule applies to the Support class mortar, get 10 kills with mortar to unlock smoke mortar rounds.
Actually the fastest way to do 180° turn is to perform the Immelmann turn.
You just pull up until you're fully inverted, then you do a half-roll.

It seems to be possible, although I think this video might have been made during the beta:
(Some NSFW language in the video)
He's using a scope + the slug ammunition type, and he gets the marksman award at the timecode I linked to.
