What does Old Gold represent on the corps colours?

Old Gold on the corps colours represents the original colour of a historic regiment. This choice is significant because it connects the Royal Marines to their heritage and traditions, reflecting the lineage and pride that come from their military history. The use of Old Gold in the insignia honors the legacy of past regiments and symbolizes the continuity of values and excellence in service.

The other options do not capture this historical significance. The modern uniform of the corps refers to current attire and does not represent historical heritage. Bravery in battle, while an essential quality, does not specifically relate to the colour's origins or representation. Victories at sea, though a proud part of the Royal Marines' history, is not what Old Gold itself symbolizes. Instead, it is the historical connection that makes Old Gold a representation of the original colour of a historic regiment.
