After seeing so much camo for dads, I thought I'd Google camo onesies*; I hit the jackpot. The one-piece bodysuit jackpot, that is.
The military clothing site, Out In Style has a wide range of kid clothing, including a camo diaper cover, long- and short-sleeve camo baby t-shirts, and a camo dress (available in woodland/blue pattern only).
They also have firefighter and police uniforms for babies and older kids, although "Infant sizes does NOT [sic] come with accessories (ie., handcuffs, nightstick) for safety reasons."
You'll have to find the indian and construction worker clothes on your own.

Even as you Google for Onesies, I would caution you against any attempt to turn a trademarked brand name into a generic term. Onesie(R) is a highly regarded--and carefully guarded--trademark of Gerber Childrenswear, Inc. Google, on the other hand, is apparently a random word picked out of the aether. Who knows how it came to be synonymous with searching the internet?
