Yes, they are.
No word about hunting, no word about sniping, scouts and scavengers.
I suppose we should nerf them so they will loose to everything that isn't combat engineer or RET, because they are light infantry meant for reckon and scavenging only according to description and ability kit.
They are literally called
Hunter Light Infantry, you can't get any more "about hunting" than that.
JLI have not nearly the same roll as IR Pathfinders or Pathfinders, they are hunters meant to be deployed behind enemy lines to capture points and disrupt weapons teams.
You can easily deduce this by the following: Name of the unit, only gets cloak at vet 1, and ability to trap points.
