Which Commando Unit operates from HM Naval Base Clyde in Scotland?

The correct answer is 43 Commando because this unit is specifically designated as a reserve unit based at HM Naval Base Clyde in Scotland. The role of 43 Commando is to provide operational support and augment the active-duty units of the Royal Marines during various types of deployments and exercises. This base is strategically important, and the presence of 43 Commando contributes to the Royal Navy’s overall capabilities in the region, enhancing operational readiness and support for maritime operations.

In contrast, while 40, 42, and 47 Commandos are all esteemed units of the Royal Marines, they are stationed in different locations and have their own specific roles and operational commitments. Understanding the distinct roles and locations of each Commando unit is crucial for recognizing the overall structure and operational framework of the Royal Marines.
