Why is it important to know Spanish as a military officer?
As a military officer you never know where you are going to be sent to. Since Spanish is one of the three most spoken languages in the world, it can be possible that you will be sent to a Spanish speaking country. It can be difficult to calm down situations and help the locals if you do not understand them and their cultures.
That is why learning Spanish is important to learn these days, being monolingual is no longer an option in the world we live in today.
