Caffeine and the Military?

It would have been harder to get by without coffee, it was what got us going while we were at sea, sometimes. When we had to crawl out of our rack in the middle of the night to stand watch, one of the first things we'd do was get some coffee. It wasn't the best coffee in the world, most of the time it tasted like jet fuel, but it would get you going. I don't know how well we'd have functioned out at sea with no coffee.
