Following up on this post, another article has some interesting details from what the publication says is a petition filed by one of the officers fired after the 2022 Brahmos incident:

“Although the petitioner was an engineering officer, the court of Inquiry apportioned him blame for failure to perform external checks of the combat connectors of combat missiles, which continued to remain connected to FCS Junction Box 1 & 3, while the same was not the role and duty of the Petitioner,” added the plea.

The petition said on the date of the unfortunate incident, there was no specific regulation or prohibition on the use of live weapons during simulated exercises despite the authorities being aware of the inherent risks associated with such processes and the revised SOP was issued only after the accident.
