And I would like it to be not just a decoration, but part of the game of radio operators.
In all campaigns, for all sides.

Can you tell me why they need binoculars?There are snipers, and you can write this…

There is also an idea to add an artillery strike on the technique when improving in the red branch when improving the veteran

Or add this improvement to the radio operators 2 in the blue branch ( so that this art attack is not given immediately, but only when pumping something)

They should be allowed for squad leads too.
