Click on "Clan Awards and Medals" and search for "Combat Infantry Award" ... the text says "Earn 5 awards in Assault Rifle, Carbine, Shotgun, LMG, PDW, Pistol and Sniper rifle.". But what's an award? Researching what other people have done, they would record 10 games for each weapon type (so that's, 70 games worth) where they got enough kills with that weapon type. An in-game ribbon is usually awarded for 6 kills (Assault ribbon = 6 assault rifle kills). Yet, we also have a CAG BF3 Rifleman Medal which states "Achieve 7 kills with the Assault rifle, carbine, LMG, Sniper, PDW, pistol, or shotgun in one round. Can only be awarded once per round.". But, why say that it can only be awarded once per round if it only requires one round to complete. So, I assumed that this is the award that the C.I.B. was talking about.
This is essentially what I've been doing:
Have 10 rounds with 7 Assault rifle kills
Have 10 rounds with 7 Carbine kills
Have 10 rounds with 7 LMG kills
Have 10 rounds with 7 Sniper rifle kills
Have 10 rounds with 7 PDW kills
Have 10 rounds with 7 Pistol kills
Have 10 rounds with 7 Shotgun kills
