The Medusa is an older weapon of the Imperial Guard, and is slowly losing its place as Imperial military commanders look to better alternatives to serve in the role of siege tank due to the Medusa's lack of range, armour, and ammunition capacity. The Medusa and Griffon have been largely replaced as infantry support vehicles by the Thunderer Siege Tank and the Leman Russ Demolisher Tank. The Basilisk and Manticore are also preferred due to their long-range engagement capabilities. The Medusa is still kept in reserve batteries just in case they are needed, but many Imperial commanders try to avoid using them whenever possible. Still, when an enemy wall needs to be breached or a line of heavily defended bunkers needs to be assaulted, the Medusa Siege Tank can get the job done.
