Siege infantry is a sub-group of siege units that are non-mechanical soldiers designated for siege warfare.
Siege infantry are a merger of the infantry (or archer) and siege weapon classes as they deal normal damage, and have natural attack bonus against buildings. Siege infantry in Age of Mythology deal both hack and crush damage.
Ambiguous units Edit
Petards are not considered siege infantry due to their ambiguous nature, and lacking many qualities of infantry. It is possible to consider the Slinger in Age of Empires to be the first siege infantry unit in the series, because of his attack bonus against fortifications and because of the upgrades that affect (and do not affect) the unit.
Age of Mythology Edit
Siege infantry was properly introduced in Age of Mythology: The Titans.
Age of Empires III Edit
Siege infantry also appears in Age of Empires III.
