Argentine Army officers wear their rank insignia in shoulderboards. Generals and Senior Colonels may be distinguished for the red trim of their shoulderboards and around the suns denoting their rank; they also wear golden wreath leaves in their coat lapels. The suns for officers below the rank of Senior Colonel are metallic; Senior Colonels and Generals have gold-braid suns.
The highest rank an Army officer may reach is Teniente General (Lieutenant General). This rank is held only by the Chief of the General Staff of the Army. The only exception is the Chief of the Joint General Staff, if he should be an Army officer. There are mentions of the rank of Capitán General (Captain General), but it is a purely honorific rank bestowed posthumously upon José de San Martín.
The rank of Senior Colonel is an honorary rank for long-serving colonels who have not been promoted to Brigade General; the rank is considered inferior to Brigade General but superior to Colonel. Senior Colonels may be further promoted to general ranks.
