I'm trying to pick which sub class I want, but I could use some help figuring out the specifics on certain weapons.

For Marksman, it says it affects Laser Rifle and Advanced Laser Rifle, but I cannot find these weapons in the creative menu. I'm guessing at least one of these is the LS-45 Laser Rifle, but I'm not sure which.

I also really enjoy using the Light Scout Rifle, which isn't listed in any class, but it looks like a sniper so I'm wondering if Marksman affects that too?
