To repeat what has already been said, seing as you love pointless repetition so much:
Snipers have 45 sight range
Pyro Sections have 42 sight range
Other recon squads like JLI or Pathfinders have 50 sight range.
Snipers with veterancy permanently have 54 sight range
Pyro Sections with veterancy have 52 sight range and only in cover
They're on curve.
Let’s play a game: spot the mainline infantry
Now another game: Spot the infantry that can build a trench for its MG with extra vet 1 range
Now another game: spot the infantry that can call in cheap smoke
Now another game: spot the infantry that just got 0.2 moving accuracy modifier buff
