The Siege Unit was designed as a mobile fortification destroyer with ramming and mortar capabilities. In robot mode, the Unit features posable fingers and it's main feature: The High Impact Rocket Ram located in it's chest. The ram is powered by a rotating Booster Jet located on the Unit's back, however, this is more unstable to use in robot mode. The Unit's high armor quantity and various shield generators makes it slow but resilient. In siege engine mode, the ram is much more effective and powerful; capable of destroying the toughest fortifications. Also used in alt-mode are two sets of Twin Energo Grenade Launchers and a set of unique treads that are capable of suspending the Unit over trenches, assuming there is enough width for them to make contact.
