подвиг(You took Winterfell with fewer than thirty men, a feat to sing of. • the brave feats of ordinary foot soldiers • Arranging the treaty was a diplomatic feat)
достижение(The trainees won twenty-nine of thirty races, a feat that may be unequaled at any level of the sport. • They climbed the mountain in 28 days, a remarkable feat. • A cargo ship is a huge and stable structure, a feat of engineering. • That was 24 years ago but now the Bees are pushing to repeat that feat.)
