Running diesel engines on military equipment is as much about interoperability as it is about fuel stability.
Diesel engines have their place. There are upsides, and major downsides, just like running a SL6, SB, or BB.
That said, there are plenty of "tough guy" types out there running 3/4ton diesels and BB A-bodies, and plenty of legit BAMFs driving SL6s and V6 EcoBoost trucks :)
