But what does it mean to be environmentally literate when you are a soldier? Three conditions need to be met to qualify.

The first is that they need to have a positive attitude towards the environment in which they execute their mission, be it training, routine base management, disaster relief, peace missions, or actual fighting. Secondly, this must translate into environmentally beneficial behaviour while executing their missions. And thirdly, they need to have the necessary knowledge to be able to act in an environmentally responsible manner.
