The Union is a playable unit in Metal Slug Attack, first unlockable via the Extra Ops titled "Agent Sally". It also appears as the daily boss in Attack! every Wednesday (or Tuesday, in lagging time zones). Parts can be obtained through Another Story.
A fairly slow and expensive unit, the Union deploys using an invulnerable "merged" form, but then later disassembles into the three segments so as to attack; a Head Tank (No. 1), a V.T.O.L Gunship (No. 2), and a Slave Tank (No. 3). The Head (No. 1) specializes in melee attacks. The V.T.O.L Gunship (No. 2) specializes in ranged attacks. The Slave Tank (No. 3) uses both ranged and melee, though it primarily uses ranged attacks.
The skills of the Union compliment each section separately: the first grants No. 1 knock back, the second bestows No. 2 with criticals, and the third allows No. 3 to stun enemies. 4 simply boosts the health of all segments.
All of the Union's attacks are listed as "Divide", since they are attached together. This does not apply once they divide.
Ram (Spread) - The Head Tank (No. 1) rams enemies with its tracks. Slave Tank also performs this attack if there is an enemy within melee distance.
Energy Projectiles (Spread) - The V.T.O.L Gunship (No. 2) and Slave Tank (No. 3) attack the enemy with energy projectiles.
Unison Fire (Spread) - All parts of the Union fire in unison: No. 1 fires heavy missiles, No. 2 fires a machine gun salvo, and No. 3 rains down parachute bombs.
- With 1 unlocked, Unit 1's attacks have a chance of knockback
- With 2 unlocked, Unit 2's attacks have a chance of dealing critical hits.
- With 3 unlocked, Unit 3's attacks have a chance of stunning the enemy.
