How do I solve 1 down in Express Cryptic 20260622?

Question

Accepted Answer

1 down reads "Final delivery for military call" (4,4 letters); the answer is LAST POST. It's a charade: the answer breaks into parts in clue order, each part clued by a word or short phrase. No indicators needed; watch for standard abbreviations (RA = artist, US = American, IN = at home) and short synonyms. The full step-by-step breakdown is on this page.
