OK, there are no missiles, tanks or fighters in FedEx. But allowing for some core differences in mission, there are a heck of a lot of similarities, logistically speaking, between delivery giant FedEx and the DOD.
Both use jet fuel and gasoline at prodigious rates as part and parcel (pun alert) of getting the job done. Both are experimenting with efficiency technologies across the enterprise, including hybrid ground vehicles and process improvements like shutting down jet engines whenever possible (and only on the ground) to conserve fuel. On the facilities side you'll find a few solar and geothermal sites. Sound familiar?
I think there's a lot to be learned here, and hopefully, AF and other leaders are taking good notes.
