selil, that is very true the MP unit in Montgomery has already served 2 tours in Iraq and it puts a big dent in LE manpower on the street. MP units are very useful during disasters,riots,etc. so your question about why there are not more is one that should be looked at again. On the other hand during Katrina one of the most used assets down along the coast of Al. and Miss. was the USMC amphibious tractor units, helicopters were over taxed to say the least but the am-tracks could go anywhere. I thought this was strange because if my memory serves me correctly the am-track was originally designed to rescue Hurricane victims and the USMC modified for use in WW2 Ops. Seems like coastal area NG units would have more of this capability.
