How about the King of Rock &
Roll ?
Elvis served for 2 years in the US Army after receiving order to
report in Dec 1957 @ age of 23 when he was already a star.
He reported for BMT in Mar 1960 @ Ft. Hood, Texas and was assigned
recuit #55310761. After completing he training, he was then posted
to the 3rd. Armored Division "Spearheads" in Germany where he
served for eighteen months. His mum past away when he was serving
there.
I salute men who answers to duty call.

Side note:
Colin Powell in his memoirs "My American Journal," recalled one day
on maneuvers:
"'Hey, Lieutenant,' one of my men
shouted. 'Come on over. Look who's here.' I walked over to the
jeep, where a grimy, weary-looking sergeant saluted me and put out
his hand. It was Elvis Presley. That their father had shaken the
King's hand astonished my kids. What impressed me at the time was
that instead of seeking celebrity treatment, Elvis had done his
two-year hitch, uncomplainingly, as an ordinary GI, even rising to
the responsibility of an NCO."
