If you need any hints for a combat badge, Look below: (Cannot think of pistol combat or knive combat)
If you need Engineer Combat Badge:
-Unlock the MP-7 when promoted a rank. The MP-7 is a little better than the MK3A1, M11-87, S12K, and the NOR982 because the MP-7 is not a shotgun.
If you need Sniper Combat Badge:
-If you are playing a map that has an uncapturable place, (which is a main base) go to that place and snipe all the enemies on a hidden spot.
If you need Anti-tank Combat Badge:
-Try finding a group of people very near to each other, take out your SRAW/Eryx, (of course, find a hidden spot) and try destroying as many people at a time with your SRAW/Eryx.
If you need Assault Combat Badge:
-Do the same thing with the Anti-Tank, but use the grenade launcher (aim with care!).
-Try to destroy an enemy helicopter that is full of people in it. At least, if you destroy one full enemy helicopter, you can get the Basic Assault Combat Badge.
If you need Spec-ops Combat Badge:
-Put C4s around your own flag in case enemies capture it. Also hide. If they do capture your flag, immediately take out your RC-90 (detonator) and click! There must be at least five people near the C4s to get the Basic Spec-ops Combat Badge. (Don't go too far away, or if you detonate far away from the C4s, the C4s won't explode.
If you need Medic Combat Badge:
-Do the same thing with the Anti-Tank, but use the frag grenade.
If you need Support Combat Badge:
-Unlock the PKM, because it does the most damage per shot than any other LMG (Light Machine Gun).
Also, there is an easier way to get a combat badge if you are good at being a commander. You can first hide where hopefully no one sees you. Then, you can Scan, UAV, Artillery, and Supply Drop.
