侵しん略りゃく
侵略 is a more common and general term for invasion or aggression, while 来寇 is a formal, literary word specifically for an enemy coming to attack.
襲しゅう来らい
襲来 also means invasion or raid, but is more common and can be used for natural disasters (e.g., 台風の襲来) as well as military attacks.

Compound of 来 (rai, 'come') and 寇 (kō, 'invader, bandit'). The kanji 寇 is relatively rare and carries a strong sense of hostile incursion.
