The SWAT team of Azur Lane

The Special Rescue Battalion and the Special Boat Unit are two police tactical units at the Republic of Arabistan. A nation devasted by a three sided civil war between an authoritarian government, the rebel army, and islamic terrorist groups.

The two SWAT teams are part of the Southern Defense Forces, a Christian militia at the south of the nation that seeks to protect the religious and expat minorities, combating terrorism at land and at sea.

One day, during a battle against Daesh troops, the two squads are caught in some form of storm and end up in the coast of an unknown island in the middle of an alternat WW2 battle.

Now stuck in this mysterious universe, the two SWAT teams decide to reside there, joining the faction known as Azur Lane, providing support against the Red Axis and the alien threat known as Sirens, fighting enemies they have never seen before, earning the name 'Azur Lane SWAT'.
