Normal shot are also different since UKF sniper has 100/85/70 penetration and 60 damage and normal shots have chance for critical as far as I can remember.
Generally speaking UKF sniper has a very weird design since it can be used again micro light(and light to some extend) vehicles which are units that are considered "hard counter" to snipers.
A remnant of the time when UKF's only access to snares was from the sniper and the mines engineers could place.
I'm sure this poses a bit of a problem for OKW trying to counter the brit sniper though, if they can't even use le goobel.
