User blog comment:A Lonely Nomad/ALN'S guide to the mg4/@comment-1977621-20100616123201

Good Guide though! One setup I use for most LMG is: OMA, Hardline, and Setrep Extended Magazines C4 UAV, Care Package, and Sentry Gun Mostly use this for Cover fire for teammate to help distract enemies, and Lewer them to me. And Place C4 for when they try to kill me as my team circles around them. Setrep to tell them of Claymore/TI's. People I play with are very talkative about what happening or choke points. Uav to see Enemies, Care Package for Bait (unless good Teammates can take), and Sentry to help me with cover fire so I dont die.
