I just didn't want to go down that rabbit hole since it's a complete tangent -- I mean you do get the Commisar squad who has UKF style healing; urban defense's conversion + structure (though that has a fuel cost); and the new airborne has the medic crate drop from the forward post.
All of that is beside the point though since neither one is forced into teching that but as OKW the nades/fausts are auto-teched and so the only apt comparison for soviets' molotov + AT nade.
I did specify non doc healing. Doesn't make sense to talk about doctrinal alternatives when comparing teching costs and core infantry. But like I said, OKW Can skip the medics (and often do because of mech truck meta) while Soviet the medic cost is more or less inescapable.
I agree it's better to not even count it into this equation.
