The yesterday report by Fars quotes an unnamed official as saying two other members of the Guards were wounded in the midday clash with "counterrevolutionary armed guerrillas" near the Kurdish town of Baneh, some 488 km west of Tehran.
The report did not name any group but the area is scene of occasional clashes between government forces and rebels.
This was the most serious incident between the two sides since April 2012, when four troops from the Guards were killed in clashes with rebels in the Kurdish area.
