The Jungle Ops CARB-15 and Night Ops CARB-15 are weapons in Jagged Alliance: Back in Action. Both weapons share the exact same statistics, only their appearance differ.
The Jungle Ops variant is available to players who own the Jungle Specialist Kit DLC, while the Night Ops one comes with the Night Specialist Kit DLC.
Bobby Ray automatically ships one for each owned kit, alongside other kit items, to Drassen Airport soon after it has been liberated.
Note that only one weapon of each kit is available per game, no others can be obtained normally.
