Also, the US mil is notorious for wreaking ecological havoc and environmental disasters, and poisoning enlisted personnel. (Ask my dad how that Agent Orange exposure was on the flight line.) This is par for the course.
While I won't disagree (lost an Uncle to Agent Orange related cancer), it makes sense that the military won't run these vehicles with extra emissions equipment on them. Besides not being suited to running JP8 fuel, the mechanisms just aren't mature yet. The reliability isn't up to par and it wouldn't do to have vehicles hit a regen cycle or enter limp mode at a bad time.
