Starship Troopers and Apocalypse Now
I just realized, Verhoeven is a fan of Coppola. I identified two thingies in Starship Troopers, lifted straight from Apocalypse Now:
1. Death from above - tattooed on the four friends' arms, is Bill Kilgore's motto, painted on his helicopter and cards he leaves on his catch.
2. Rasczak bringing footballs and beer and violins to the troops after the fight, is Bill Kilgore bringing beer and surfboards and guitars to the troops after their fight.
