NOTE - Do not take this very seriously 🙂
I highly doubt the devs would ever add smoking or alcohol to the game. But I would love to smoke a lucky strike while im big chilling in a foxhole 😄 Commander gets a cigar maybe 🙂 You could find cigarettes on dead enemies if they had them and alcohol. Along with that item's like flags, lugers, watches etc for keepsake. Keepsake items are for... Well idk? Boost morale? Manpower? 😄 but I can imagine a version of HLL that had some mechanics in place where players would smoke, drink and search the bodies of enemies for one reason or another. It just feels good to conquer the enemy and take something from them.
