Yeah, it does. 150+100 marksmen makes a Marksmen ribbon. After learning about that, it's a little easier than doing 5 headshots (okay, not quite since it requires distance whereas BF3's Marksmen could've been gotten with ALL weapons at all ranges) since you just have to calculate a good range to combine into 250 with 1 or a few more shots.
Problem is I don't play sniper often enough since hitting moving targets is a damn impossible thing for me to where I line up headshots often enough for that. I think I have like 6-10 marksmen for the 50 required for the last sniper that isn't a weapon EXP unlock.
