Which guns are the light machine guns this assignment is talking about?
Which are the "Light Machine Guns" they are referring to here?
Here and Here are possibilities.
Solution 1:
Any gun in the Support class counts as an LMG:
- M249
- PKP
- M240B
- M60E4
- M27 IAR
- RPK-74M
- TYPE-88
Note This does not include guns that the support can use, only guns that are exclusive to the support class. So any multi class gun is not a LMG. Just because support can use it doesn't make it an LMG. Some guns that don't count:
- PDW-4
- UMP-45
Looks to me by your battle-log that you only have the M249, so spawn Support with that and rack up those kills!
