Step 1 : Introduction to the question "Which of these countries in Central America does not have a standing army?"
...While it might seem normal for every country to have a military, there are some that don't have any armed forces whatsoever. The CIA World Factbook lists nearly three-dozen nations and territories without armed forces, many of which rely on other countries and international groups to provide their defense. There have been no armed forces in Costa Rica since 1949. The country, which is often referred to as "Switzerland of Central America", proclaimed its permanent and unarmed neutrality in 1983. In fact, Costa Rica is protected by the United States.
