Homestyle Garlic Ranch Dressing. Make your own garlic ranch dressing using mayonnaise, buttermilk, hard-boiled eggs, and plenty of garlic powder. This dressing packs a punch of flavor and explodes with freshness, a bit of tang, and traditional ranch flavor. This is for those who prefer herbs rather than spice.

Diesel-electric submarines can last 2-3 weeks under water before resurfacing. Diesel/battery submarines do not dive very deep. These are quick attack sub's and often carry cruise missiles that they launch from just below the surface. There is special machinery on board that recycles and purifies the air.
