As far as using military bases to house refugees, I'd say it was a great idea, but most of the bases that are closing are closing because the infrastructure in the base needs huge $$$ to remain effective. When Fort Devens in Mass was closed, the proposal was made to take the military housing on Devens and use it for low income and homeless shelters. The answer was that it could not legally be done, as the base housing (fine for soldiers) was not up to section eight standards, and the liability that would be incurred by using old buildings with asbestos in them would be astronomical.
The military has a lot of battery powered equipment, and the LA National Guard has battery powered equipment, but the Governor of LA did not call out the National Guard until it was already too late.
On the Positive side, the Military side of the Relief effort is being led by LTG Russell Honore. If there's a way to get it done, He'll find it. I spent my last year on active duty up at FT Drum under his command. His orders to his staff are simple.....Get it done. If it doesn't get done, there's hell to pay. (Note to the Mayor of N.O. ......stop whining, it isn't going to win you any points in staff meetings) His "nom de guerre" is the Ragin Cajun.
