peaked caps, in either light tropical khaki and Olive Drab wool cloth, which slowly began to replace the campaign hat in service dress. The khaki US M1934 sidecap (a.k.a. 'garrison cap') was also supplied to GN personnel during the 1930-1940s. Guardia uniforms underwent some changes in the 1950s and 1960s, with officers adopting the US M1942 light khaki service dress, comprising tunic, slacks and a matching peaked cap with brown-japanned chinstrap and peak, or black dress cap with gold chinstrap, black peak with gold leaf embroidery for field and general ranks (the GN Chief Director had additional French-style embroidery on the cap band), and silver triangular national cap badge. For formal occasions, senior officers adopted a black ceremonial version of their M1942 service dress with gold embroidered insignia whilst the other ranks' retained the old khaki 'Chino' uniform as barrack dress or for walking-out, usually worn with the khaki sidecap.

Their male counterparts retained the 'Montana Peak' Hat as standard headgear, though the latter also began to be replaced by a light khaki M1954-type Visor Cap; Police officers on traffic control duties were given a white-topped version. It never entirely superseded the earlier headgear however, for photos taken in Managua at the time of the 1972 earthquake show local policemen going on patrol still wearing the old 'Montana' Hat.
