RCM Lieutenant's Cap is an item in Disco Elysium.
The cap is sturdy and comfortable, and seems to retain its form very well. It fits you perfectly. The inside of it smells... like cheap tobacco and typewriter ink. It feels familiar somehow. Perhaps it, too, is yours? Though how *the pigs* got it is a mystery.
