invasion
Hostile territorial entry
An invasion is the entry of a military force into territory to conquer or occupy it: the invasion of Normandy.
The word extends to any unwelcome intrusion in large numbers: an invasion of tourists, an invasion of privacy.
Invasive species spread aggressively into new ecosystems.
Medical procedures are invasive when they enter the body.
