M-42 Anti-Tank Gun
Imo the ability should either be remove or made useful, the current solution seem to turn it into a useless option.
Suggestion:
Canister either removed or turned into a single shot with a small munition cost that does damage but remain weak.
M1910 Maxim
The ability is rather difficult to use since it take time to prepare.
Suggestion:
Reduce the time (or remove the) to reload of the unit.
Make the ability scale with veterancy even moving to vet 0.
Conscripts
Does the bonus gain in veterancy mean faster XP gain or lower XP value?
The bonuses of lower reinforcement cost more durability and faster XP gain are enough on their own the unit does not need more DPS. Keep in mind that conscripts do not need to win the fight the can win via attrition especially vs 4 men squads that have a high reinforcement cost.
The combination of ourah and cover bonuses make this unit too flexible especially vs grenadier.
If one want to solidify upgrade conscript as a defensive infatry one should simply redesign the abilities of the unit.
Suggestion:
Either simply remove the cover bonuses and lower MU cost for the upgrade
or
Redesign the abilities on the upgraded unit.
1) Ourah replaced by hit the ground (ability could scale with veterancy)
2) Molotov replaced by frag grenade
3) Range of At grenade increased
These changes would solidly the unit as defensive oriented unit.
I also warned of a few things like Jaeger buff, but there's no reason why your word should be gospel.
M42 needs to be treated delicately or it will end up a poor mans ZiS
