"Kamikaze" is a Japanese word meaning "divine wind", that has an English meaning of "suicide pilot". It got this meaning in English because during World War II, the Japanese called naval pilots who deliberately flew their planes into American warships "kamikazes".
"Juramentado" is a similar word for Moro jihadis who made suicidal sword attacks.
"Berserker" is a similar word for Viking warriors. The Viking berserkers often survived.
"Desperado" is a similar Spanish word for a desperate fighter, especially in the context of the American "Old West".
"Diehard" and "holdouts" might be the closest English words that are not "borrowed" from another language. In the "Die Hard" movies, Bruce Willis' character was victorious, despite very long odds. "Diehard" is also used for a brand of long-lived automobile batteries, and for people who stay in a game, business, or career after most others have quit. The last opponents in a siege or war to surrender might be called "holdouts".
Most Americans would understand kamikaze, berserker, desperado, "diehard", and "holdout".
