Aggression表示侵犯进攻时含义较广，既可指武装入侵别国领土，又可指文化、经济等方面的侵略。强调敌意和挑衅。如：unprovoked military aggression无端军事侵犯，the threat of massive military aggression. 大规模军事攻击的威胁。

Invasion表示侵犯时常指侵犯【别国领土】，如：the Roman invasion of Britain 罗马人侵入大不列颠岛。在表示对他【人权利】的侵犯时也用该词，如：an invasion of privacy 侵犯隐私。

Assault在军事上强调突然而猛烈的进攻，即【突袭】，如：launch an assault 发起攻击。在法律英语中表示对【对他人身体的侵犯；侵犯人身罪】，如：indecent assault 猥亵（罪）；猥亵侵犯他人身体，sexual assaults 性攻击（指强奸、猥亵）

Offensive在表示进攻时常指大规模的协同【军事行动】，和assault的第一种用法类似，但不强调突袭。如：an air offensive 空中攻击，take the offensive 采取攻势。

④The Capital Airlines episode is illustrative of several key issues: the importance of Aweys’s personal leadership in armed opposition to the Transitional Federal Government and AMISOM; Eritrea’s direct and overt support for his return and the subsequent reinvigoration of Hizbul Islam in preparation for its offensive of May 2009; and the degree to which weak regulatory frameworks in some States of the region — in this case Kenya — enable sanctions-busting behaviour of the kind Capital Airlines engaged in.
