From the outset, the Guard has endeavoured to produce authentic reconstructions of Roman armour and equipment, and as more information comes to light, the Guard updates any incorrect equipment that has been made in the past.

The Guard makes 90% of everything on display including the cavalry equipment and artillery as well as all infantry armour, the tents and other equipment.

This process works both ways. The Guard actively seeks out and studies newly discovered research and updates their equipment accordingly, and academics use reconstructions created by the Guard in the understanding of the function of certain pieces of equipment.
