The American Red Cross has 400 Emergency Response Vehicles (ERV) in the country.
During Sandy, the entire fleet deployed.
Each ERV can distribute up to 300 meals at a time, so usually it's breakfast, lunch, and dinner.
The vehicles are packed with supplies such as food, water, cleaning kits, hygiene kits, and comfort kits for both children and adults.
Right now, the American Red Cross has 30 ERV's deployed to Oklahoma.
