The Armourer Sergeant is responsible for the maintenance and management of the Regiments arms and ammunition. As a re-enactment unit every individual soldier will be expected to keep their personal arms and weapons well appointed and in a safe working order. The Armourer Sergeant reports directly to the event coordinator during re-enactments and public events. Any instruction regarding the safety and security of weapons and ammunition at re-enactments and public events must be obeyed. Failure to obey any safety instruction will result in Regimental disciplinary actions being taken and may result in Police prosecution.

The 80^th Regiment was equipped with the India New Land Pattern (Brown Bess) Musket for its Australian service. This lighter and shorter (39-inch barrel) musket became the preferred musket of manufacture by the Board of Ordnance for the British Army in 1797. Prior to this, this pattern was developed and adopted by the armies of the East India Company, hence the name.

A well-trained soldier could prime, load and fire three times in one minute. This involved a 12step process in order to fire just one shot. Also, these muskets did not fire bullets, as we know them in the modern sense, but fired round lead balls, some of which were the size of a ten cent coin. At short ranges, these lead balls could inflict horrible damage on soldiers as they did not pierce a person's body but rather smashed against it.

The firepower of the British Infantry was certainly destructive but it was the bayonet that often delivered the coup de grace. The bayonet was frequently the deciding factor whenever the British locked horns with the French. The attacking French column would be met by a silent wall of redcoats, when the range was right, the order was given and the resulting volleys would blow away the head of the column. The British would fix bayonets, then after a rousing cheer (HUZZA!) would advance to finish off the French, who more often than not would not stand to face the cold steel of the bayonet.
