Yeah, very smart.
So no need for Maxim fix if there is a default problem since doctrines is all you need. You got a spare SU MG (that doctrine MG), so no fix. Katitof thinking. Very smart.
You cant fix a problem by just using doctrines. It is dumb mechanic.
Doctrines should be additions, not fixes to problems!
MGs role is to suppress infantries.
Maxim doesn't do that.
Engineers role is to sweep mines, plant mines, put occasional wire or cut it and repair stuff.
Spios most certainly do all of that very well + shitload of extras.
You want to fix a problem that doesn't exist outside of your head.
Spios are NOT AT squad, but they can supplement puppchens.
Spios are NOT AI specialist or even generalist, but they can supplement volks.
