SANDF spokesperson Siphiwe Dlamini said on Monday that the members were released on Friday.
Dlamini said the members will face charges of housebreaking, theft and the loss of firearms.
After the report of the theft, the DA questioned how the break-in had happened, saying there were questions the SANDF had to answer.
DA shadow minister of defence Kobus Marais asked whether the theft could have been an inside job, where the guards were positioned during the incident and why they failed to foil the break-in.
“This embarrassing robbery is a symptom of bigger problems in the SANDF,” Marais said.
