Holes in front bumper

[JCJ]

When I got my Hummer in August I saw there were three round holes on the horizontal (top) side of the front metal bumper, below the grill.
Two have a black rubber "stopper" in 'm.
The middle round hole was left open.
Anyone knows for what these holes are intended?
Something to do with the optional front whinch?
Other ( /infopop/emoticons/icon_biggrin.gif) suggestions are also welcome.
