How does a military magistrate take part in pretrial investigations in some countries?

In many military legal systems, particularly those outside the Anglo-American tradition, a military magistrate plays a central role in the pretrial phase. In these jurisdictions, the preliminary investigation is typically placed in the hands of a military magistrate, a process often initiated by a military procurator who is responsible for bringing prosecutions on the public's behalf.1

Additionally, in systems where an accused service member is held in arrest pending trial, a military magistrate may be required to order and authorize that arrest, often for a limited duration, to ensure the protection of the accused and prevent unjustifiable detention. This involvement serves as a safeguard within the military judicial process, distinct from systems where the commanding officer holds primary responsibility for the investigation.21
