"We introduce McMillan Tactical Gear by Eberlestock with the launch of what many will see as the ultimate scout/sniper pack, the Operator.  It represents everything that Eberlestock has learned about the needs of the professional military sniper community.  It is a true go-to-war pack, derived from the lessons learned from our Phantom and Gunslinger products, and augmented with the first-hand knowledge of the Navy SEAL who is at the helm of McMillan Tactical.  Together, we think we're going to rock some boats with gear that the free world's warriors desperately need.  Have we succeeded?  We invite you to be the judge." Excerpt from Eberlestock Factory website.

The Eberlestock Operator is a behind-the-torso pack, and places the weight of your weapon right along your center-of-gravity.

When shooting from the pack, you have direct access to all of the pockets.  The side pockets peel back to expose PALS-type webbing that can be used to mount ammo or other items. The Operator has elements similar to other Eberlestock packs.  Its layout is much like the Phantom, but it's bigger and has a two-chamber main compartment, plus the outer front pockets.  Like the Gunslinger, the Operator's pack bag and Backscabbard™ are sewn integrally together.  They built the pack to satisfy the reality that a classic "drag bag" is rarely likely to be used by a modern military scout or sniper, and we gain some benefits of simplicity and weight savings by integrating the whole package into a single unit.
