You are assuming the maxim was designed to be used like the mg42 as a defensive unit, it was implicitly stated by relic that it was designed as an offensive unit to be moved with infantry on the go. Hence its speed and packing time, yet bad suppression and terrible firing arc.
If you cant flank a maxim then your micro is terrible. Two squads, run toward the maxim (dont even need to bother flanking it outright) one or both will be able to run right past it without being suppressed, if he starts packing up, move behind him, repeat and repeat until hes dead or retreats. Its not rocket science, it happens to me all the time.
This is some high level shit man, who would have thought that flanking MGs with no packup time could be that hard.
Maybe.... maybe.... if they built 2 mgs to back up each other, then they would easily cover both squads, not to mention pull back the first mg.
Most of us in coh2.org have played coh1 so we would know how to flank an MG42 tyvm.
