It is weird that the military version looks like an afterthought. Especially the N492SA looks like "frankencopter", with bits of equipment just bolted into the skin, like it never should be there according to the overall design (not to mention the paint shame).
While the civilian versions have sleek and clean lines. Just by the looks, one can come into conclusion, that this wasn't design as a military platform, therefore could assume, there is no provision for auxiliary fuel tanks, nor enlarged sponsors (MH-53E style) as those should be shown already somewhere.
