Squad Leader Archive

I just got into an argument with my neighbor (who has the strat guide) about requirements for squad leader. I believe it's the entire survival tree line and the entire ranged weapons tree line as oppopsed to master marksman and master scout is this true?

And does anyone know of a way in which to gain quick exp for ranged combat. I have been trying to blast everything in sight from the optimom range for the weapon I'm using

The requirements for SL are the entire Survival tree, Exploration tree, and Ranged combat support tree, as well as an aditional 7,500 combat Xp.

As for the combat XP issue, no real easy way i've seen. Only way i know of to get the most is to kill the target by yourself. That, or trade in faction points for it.
