We used to get that shyt too. But we didn’t tolerate smoking while on patrol in the gunboats. Off duty only.
Of course there is no “off duty” in the field. But we used to get 12 on 12 off, 24 on 24 off and 36 on 36 off patrol sectors. So we had a lot of rear area time.
Isn’t there a certain risk indulging in that when you could be attacked at any time? Your superiors may gave you time off, but that doesn’t mean the enemy will?
