invaders
Unwelcome armed arrivals
Invaders are people or forces that enter a place by force, typically with hostile intent.
Armies invade countries, pests invade gardens, and unwanted thoughts invade the mind.
The word carries connotations of violation and unwelcome intrusion: The invaders burned the village.
In science fiction, invaders often means aliens attacking Earth.
