kidney shaped mugs?

Looking around at kit a lot of the mugs seem to be kidney shaped, there must be a reason for this shape but can't figure it out.

The kidney shaped water canteen fits into them better that way, else you'd need to use a hammer and could damage one or the other.

Ok that will it explain it then but next question why is a water bottle kidney shaped?

I think the military water bottles are kidney shaped so they sit more comfy against your back when in there pouches(though i could be wrong)

I would imagine, but stand to be corrected, that it could be a better shape to wear on a webbing belt as part of daily essential carry kit.

Because most people buttocks aren't flat but have a natural curve. The kidney shape follows that curve... as has been said already.

Simples.

A rubber mallet might cause less damage....

that kidney shape of the U.S. canteen and cup follow the shape of your hip/backside...they lay better against those areas than a round one or oval shape...vince g. 11B INF...
