Well, for me it got to be the one shot raveshaw or sydney.I particular like it when it also functions as a sniper rifle if u have good eyes and anticipation.
Once, i was using it and on a hilltop shooting at tanks when there is no infantry and shooting at infantry when there are no tanks...heh heh.
On a average, i take bout 2 shots to kill a infantry allowing one shot for missing.
I think light armours like MRLS and buggies can only take at most 5 shots before expiring...
So, it is much better than the mobius gun. The range is shorter so you need to get up close and personal definately a disadvantage when you meet multiple infantry or the danger of being run over.
Just my opinions.
Thank you.
