The term "Ejército" refers to a military force organized for land warfare. It is typically composed of various branches, including infantry, artillery, and armored units. The primary role of an ejército is to defend a nation’s sovereignty and maintain peace and security. In many countries, the ejército is a key component of national defense and may also be involved in humanitarian missions and disaster relief. The structure and size of an ejército can vary significantly depending on the country's needs and resources, with some nations having large standing armies while others maintain smaller, more specialized forces.
