I reckon tranche 2 of Land 159 has all 3 types of machine guns covered, LMG, MMG and HMG. Where they employ them, is another story all together. With 3, 6 and 7 having 30mm cannons sooner rather than later and 1, 5 and 8/9 having what ever they can strap on a CROWs mount on a PMV, maybe they start thinking they don't need dismount belt fed weapons. I fear that would only last until the first contact though.
I don't think they've even nailed down section sizes yet, is it 6 in the back and 3 crewies, or are they squashing 8 in and the crew?
