Not trying to rain on your parade jay but these links are links that take you to the battlelog log in page.

What you want to do to provide the correct link as follows is -

Log into your battlelog

Click on your soldier as this will take you to your soldiers progress page/your stats page.

Here you will want to click on battle reports

On the next screen on it will show you every game that you have played to date(if your hardline premium it shows 26 weeks worth I think) otherwise its limited.

Here you'll want to find the games that you played with recent CAG members which you can do by clicking on each individual game.

Once clicked this will bring you to the report game of that page and show your score,kills etc everything that we need to see that your kills where not obtained by explosives or vehicles.This is where you will was to take that link from with copy and paste.

Any further questions or complication with your links just ask who you ar online with doing your marksman as everyone has went through this process and should be able to talk u through it step by step.
Other than that man everything else with the format is good.Just a tip you'll want to post every game for your marksman within this thread until completion is achieved.
