Suicide units are units featured in Age of Empires II and Age of Empires III that self-destruct by exploding when they attack, which does damage to nearby enemies. Hence, they can only be used once. They hold a great attack and deal splash damage. Also, most of them have an attack bonus against buildings. If they get killed before reaching their target, they will explode anyway and might still do damage if close enough.
In Age of Mythology, there are two units that take this role, but they can only attack one unit at the time and they do not deal splash damage.
Note that explosive suicide units do not realistically, automatically chain explode other explosive units. Other units only explode when their hit points reach zero, regardless of how damage was taken. For example, a Demolition Ship exploding into five enemy Demolition Ships will not suddenly cause all five enemy ships to suddenly explode; they will only take standard damage.
Age of Empires II[]
In Age of Empires II, there are two commonly available suicide units (one of them being an evolution of three units), one unique unit, and one available only in the Scenario Editor and campaign scenarios:
- Petard
- Demolition Raft → Demolition Ship → Heavy Demolition Ship
- Flaming Camel ( Tatars only)
- Saboteur (a hero and cheat unit)
Age of Mythology[]
In Age of Mythology, there are two suicide units only available in the campaigns and Scenario Editor. Both of them share the same icon, texture, and animation, but the first one is invisible to enemies and kills most human soldiers and myth units in one blow, and the second one only attacks enemy myth units:
- Shade (SPC) (appears in Strangers and Good Advice)
- Shade of Olympus (appears in Mount Olympus and Yin and Yang)
Age of Empires III[]
There are two suicide units in Age of Empires III, one on the land and the other on the water. Another naval unit cannot be trained and only appears in the campaign, it is available to the Maltese though the Greek Fire Home City Card in Age of Empires III: Definitive Edition - Knights of the Mediterranean.
- Petard (added in The WarChiefs)
- Fire Junk (added in The Asian Dynasties)
- Fire Ship (campaign and Maltese only, based on the Caravel).
