People generally give Pathfinders a BAR, otherwise they're completely useless in combat.
It's not incorrect to say Pathfinders cost more.
Truck needing to be deployed is also irrelevant. BARs need a specific side tech to be purchased, JLI scoped G43s just need normal teching.
It's less that they need a truck and more the timing, because Jli without g43s is kind of a waste of time. Pathfinders will at least crit out of the gate.
