For civ use it's still a fantastic pack as well. At least the model I have has a couple features that made it extremely handy for vehicular duties. The gap between the lower rear pouch and the upper rear pouch (on mine) is perfect for being able to interface the lap belt on a seat, which then keeps it in an upright position on your passenger seat. That then lets you use the right hand side compartment to hold a nalgene or whatever if you have a vehicle that doesn't have a center console due to a shotgun rack or whatnot. Also, with it being upright the rest of the storage is available as well, moreso than if it's laying down or in another orientation.
