Machine Gunner
The main role of the MG is to overwatch the squad and hold longer lanes.
A good MG will be patient in order to consistently maintain his ground.
A good MG will have to know how and where to bipod quickly in order to not overexpose for too long. By reading the map, the MG will rotate and find lanes to cut enemies off / protect their squad.
Usually need good game sense to play this role properly in order to choose what lanes to hold and when/how to rotate.

The MG excels at medium to long range firefights, but is extremely weak in close quarters and when reloading. The MG is well-suited to overwatch duty, providing a Base of Fire for your squad. SL's pair well with MG's as they can use their binos to spot and adjust the gunner's fire.
