The U. S., also, has morale issues with its ICBM forces because of the dispersed and isolated nature of deployment. Maybe there needs to be either centralized or localized recreation and socializing centers built within convenient commuting range of these missile bases.
Also, because of the isolated nature of this duty, I’d think that shifts should be four hours max, with only one shift per day. Not that I’m aware of the shift details, but I think this would make duty less tedious, and also increase the total number of staff (and, thus, increase the potential number of social networks) on station. It’s not like a nation would need to scrimp on staffing bases committed to strategic national security.
When I was based in northern South Korea for exercises, we were, one day, shocked to see a virtual city appear on base-camp made up of tractor-trailer beds functioning as Burger Kings, KFCs, et c., and tents set-up as retail and service businesses. Now, of course, the USMC provided three free meals daily, but the option of junk-food and retail therapy sure was uplifting!
Also, I know that the USO used to do a decent job of maintaining morale.
