I always feel like a dick for doing this but ... a couple of things: vehicles kills aren't allowed and the kills confirmed should be obvious.
There are vehicle kills in the following games:
Post #9, 7th game listed, 2 kills
Post #10, 3rd game listed, 1 kill
Post #10, 6th game listed, 1 kill
Some games have what I'll call "unspecified" kills. Depending on how you make your kills, battlelog doesn't always show how they all happened, unfortunately. And we can't be sure that they weren't explosion kills (grenades, C4, EOD Bot, etc) which are not allowed in the Marksman count (same for Rifleman, SharpShooter, and Expert). For example, this game http://battlelog.battlefield.com/bf4...840/867382860/ ... you had 30 kills and 24 with your best weapon, where did the other 6 come from? If there was a ribbon to indicate other valid means such as a handgun ribbon or melee ribbon then that can be added in, but there isn't. You might have knifed some people but not enough (4) to get the ribbon. So, I can't really confirm those.
These are the games that had unspecified kills:
Post #9, 2nd game listed, 2 kills
Post #9, 3rd game listed, 4 kills (though I will allow 2 ...* see below)
Post #9, 10th game listed, 6 kills
Post #9, 11th game listed, 1 kill
Post #10, 5th game listed, 1 kill
Post #10, 6th game listed, 1 kill (other than aforementioned vehicle kill)
* I personally witnessed two knife kills as I spotted and suppressed the enemy while Dripz flanked and shanked them. At the time he said he had 4 knife kills but I didn't see a melee ribbon awarded.
------------------
Sorry Dripz, for using you as a teaching lesson for those who confirm games, but I've seen many confirmations that simply look at the total kills and don't confirm that they weren't vehicle or explosive kills.
