The Pikemen and Musketeers are dressed and equipped as members of the HAC would have been in the 1640s and are tasked with providing a ceremonial bodyguard and escort for the Lord Mayor of London.

It also provides period displays of 17th-century drill and music to show how the army of Charles I moved and defended itself.

The uniform company members wear is identical to that worn by the HAC in the reign of Charles I of England.

They are armed with a match-lock muskets and rest and wear a leather cross belt, from which are suspended 12 wooden gunpowder flasks known as chargers.

The form of drill used is taken from a manual entitled Militaire Discipline first published in 1638 by Colonel William Bariffe, a member of the HAC and veteran artillerist who fought in the English Civil War under John Hampden.
