Since according to you there is no difference remove tech lock on the weapon or lest give a tech requirement to ranges paras and guards.
There is a difference between timing and the cost.
You're smart boi, I'm sure if you spend enough time, you'll figure it out yourself without me holding your hand this time.
Also, last time I've checked, paras, rangers and guards weapons were not Deus Ex Machina effective at all ranges, allowing you to engage all units in game from always advantageous position.
Paras are 6 men and the are not osttruppen (airdropped units need high entity count to survive airdrop and fighting behind enemy lines).
In addition I suggested make them an infiltration unit or airdropped and PF is neither.
Its hardly relevant, you already have 6 man squad you're describing, deployment method doesn't matter.
If FG42 is problem because they are good at all range so are SVTs for the same reason.
Use that argument again when SVTs long range will be much more flat dropoff compared to close range, you know, like FG42.
As for camo try to keep up with patches, it provides ambush bonus only at VET 5 and that is the least of their problems.
Again, not relevant, its not like they struggle vs anything to get to that vet5 fast.
They got it all, great base stats, on field deployment, 2 offensive nades, faust, weapons very effective at every single distance, camo, amazing scaling.
The only "disadvantage" they have is being 4 men.
Doctrinal unit having its weapon upgrade tech locked is only a testament to how powerful it is in comparison to all other doctrinal infantries(barring the osttruppen, in case you wanted to swing that in, but I doubt you'd use something this stupid as an actual argument)
