英勋 is a literary, classical-flavored compound -
英 (heroic, outstanding) +
勋 (meritorious deed, often a military or state honor). You'll meet it in historical writing, formal eulogies, and historical drama subtitles, rarely in everyday speech. Modern equivalents:
功勋 ('meritorious service') is far more common;
英勋 has a more poetic ring.
