   敵てきの旗艦きかんを撃破げきはしました！↗

   We've destroyed the enemy flagship!

• Synonym打ち破るうちやぶるNeutralBroader than 「撃破」: it covers breaking things as well as beating rivals, while 「撃破」 stresses crushing an enemy force in battle or winning a match.
• Synonym倒すたおすNeutralThe most versatile of the group: knock down or defeat, common in everyday speech; it lacks the military sense of crushing enemy troops that 「撃破」 has.
• SynonymやっつけるCasualColloquial: to finish an opponent off or teach them a lesson, with a satisfying punch; more casual than 「撃破」.
• Synonym破るやぶるNeutralWide-ranging: to break or to beat, as in 「記録を破る」 and 「強敵を破る」; unlike 「撃破」, it is not tied to crushing an enemy in battle.
• Synonym打ち取るうちとるNeutralTo slay with a weapon or defeat an opponent — also retiring a batter in baseball; the focus is on taking down one opponent.
• Synonym粉砕ふんさいWrittenWritten style: to smash to pieces, figuratively crushing something completely, as in 「野望を粉砕する」.
• Synonymなぎ倒すなぎたおすNeutralMows down a whole row of opponents or objects — a vivid picture of sweeping, unstoppable force, more graphic than 「撃破」.
• Synonym撃砕げきさいWrittenWritten and rare: to smash something to bits with a hard blow; the stress is on shattering, and the word is seldom seen even in prose.
• Synonym打ち倒すうちたおすNeutralTo knock someone to the ground, or beat an opponent down completely, as in 「強敵を打ち倒す」.
• Synonymぶっ潰すぶっつぶすCasualRough colloquial: smash to bits or wreck a plan or company outright, charged with strong emotion; far coarser than 「撃破」.
• Related大破たいはWrittenWritten: heavy damage beyond repair — often to vehicles — or a drubbing of an opponent; the stress is on the damage done.
• Related転かすこかすCasualKansai colloquialism for knocking someone over; it has nothing to do with crushing an enemy in battle.
• Related制勝せいしょうWrittenWritten and little used: to prevail by holding the opponent down; the point is the victory, not the destruction.
• Related掃滅そうめつWrittenWritten: to sweep away and annihilate, stressing the total elimination of the remaining enemy.
• Related一本取るいっぽんとるNeutralSet phrase: to score an ippon, a full point, in judo or kendo, or figuratively to get the better of someone in an argument; never about military crushing.
• Related敗るやぶるNeutralTo defeat — normally written 「破る」; the kanji spelling itself is rare in writing.
• Related討ち止めるうちとめるWrittenWritten and uncommon: to kill an opponent with a sword, knife or spear, stressing striking the fatal blow oneself.
• Antonym敗北はいぼくWrittenWritten antonym: defeat or loss — being beaten, the opposite of 「撃破」's crushing of the enemy.

Use 「撃破」 for crushing an enemy force in battle or beating a strong rival in a match, as in 「強豪を撃破する」. For beating someone in everyday contexts, 「倒す」 and 「破る」 are the natural picks; in casual speech, 「やっつける」 adds a satisfied 'that'll teach them' tone, and 「ぶっ潰す」 is rougher still. 「粉砕」 suits written, figurative crushing, 「大破」 heavy damage, and 「掃滅」 wiping the enemy out entirely. For slaying with a weapon, see 「打ち取る」 and 「討ち止める」. The opposite outcome is 「敗北」.
