In general, the GSIC agents will wear like other intelligence agents. However, for some special units, they will have different suits for missions.
Grossvietnamese Security Service (GVSS). This is the department-level body of GSIC which is concerned with the tasks related to the protection of several high-ranking state officials (except the Royal Family because the Imperial Guard will fulfill this mission).
Phạm Ngọc Thảo Guards Corps (PNTGC). Like the Imperial Guard, the PNTGC is garrisoned in Sài Gòn. However, the GC will be responsible for the protection of government buildings and personnel externally, unlike the GVSS and GVIG.
Special Activities Groups. Special forces of the GSIC.
Special Frontier Force. This is one of two special units responsible for covert operations behind enemy lines.
VietCong guerilla units. Used for covert operations behind enemy lines. However, the VietCong's main mission is training Communist paramilitary groups in secret.

GSIC - 5D MPS
Though Grossvietnamese People's Public Security has its branches specialized in intelligence, the needs of MPS is mainly focused on the usage of security needs, not for attacks on other nations like GSIC. However, MPS and GSIC have always cooperated with each other to fulfill the missions of both sides.
GSIC - MID
Unlike the MPS who focuses more on security needs, the Military Intelligence Department has more similarities on the targets to GSIC. They both care about foreign targets more than domestic targets. So they cooperate with each other very easily, except for some minor rivalries between them in some controversial situations
