How? If they build 3-4 maxims, they'll likely be lacking sufficient AT to defend all 4. Luchs is great against maxims, as long as its flak kills the guy wheeling back the maxim, you'll likely be able to wipe it. The maxim is still the only mg who's models don't warp to the mg when they drop it on retreat, and the luchs is the best infantry chaser in the game.
1 con 4x maxims t3 t70.
Add guards at will/if neccessary.
If you play half-decent map is equal or more in your favor.
T70 then arrives about the same time as luchs, no further at needed but i like to get 2x guards after, just in case (and their AI ain't bad either).
Keeping track of where your maxims are, and their positioning is micro intensive. Along with retreating the second you are flanked/get incendiary naded otherwise your insta wiped and give them a maxim which is GG.
This is far more micro than attack moving a volks blob
I could make a similair post about how to micro volks vs maxims, but i simply leave it at the folliwng:
A-moving maxim will beat an a-moving volk.
