Vojska Gvatemale se sastoji od Nacionalne kopnene vojske (Ejercito Nacional de Guatemala, ENG), Mornarice Gvatemale koja uključuje i marince (Marina de la Defensa Nacional) i Zračnih snaga (Fuerza Aerea Guatemalteca, FAG). 2004. godine se provodi velika reorganizacija vojske koja sa 28.000 pripadnika smanjuje broj na 15.500. U toj reorganizaciji mornarica i avijacija ostaju svaka bez 1000 pripadnika. U istoj se reorganizaciji neke od 19 vojnih zona sa tri strateške brigade spajaju te se tako smanjuje broj zona. Proces se nastavlja. Avijacija ima tri baze, a mornarica dvije.
