The clashes occurred in the Keshtegan area of Saravan city in Sistan-Baluchestan Province on Sunday.
The two security forces belonged to the Quds Base of the IRGC, Press TV reported.
Two other security forces were also wounded during the confrontation.
Terrorists operating in neighboring countries, including Pakistan and Iraq, have repeatedly targeted Iranian military and security forces serving in border provinces.
On February 12, a suicide attack on a bus carrying the IRGC personnel killed 27 people and injured 13 others.
Earlier in the month, terrorists killed three IRGC servicemen during clashes in the Piranshahr city of the West Azarbaijan Province. One more was injured during the attack, which targeted a vehicle carrying the forces at the entrance to the county.
Iran has urged its neighbors to engage in meaningful and effective counterterrorism efforts aimed at rooting out the malign border activities.
In May, Pakistan started fencing its 950-kilometer-long border with Iran in an effort to strengthen security in the area.
The IRGC has said it reserves its right to chase the terrorists back into the countries they launch attacks from and target them in their hideouts.
