Seems to me that I read a few years ago that there is an international agreement barring all weapons from space, even small arms. I find the survialist angle hard to swallow given the tracking on any returning vehicle.
Yes because no nation ever violated a treaty, ever. And because big dollar technology projects never ever fail, ever. (Hubble) And that wolf chewing on your foot never attacked anyone. (Except that little Siberian girl that never made the papers here)
The Russians, from experience, prepare for the worst. I'm not saying a Russian engineer could have kept the Titanic from sinking, but you can damn well bet there would have been enough lifeboats. And your chafing dish could be used as an oar.
Russians have been doing more with less for over a century, and while we might look sideways at our former adversary's inventions, they often work astonishingly well. (Do a web search on limb re-attachment, for example)
There is also a level of machismo in the Russian Armed Forces that we westerners likely just don't get. For example, G-Suits were often NOT worn by Soviet pilots, because they were for 'pansys.' Russian special forces were trained in extensive hand to hand combat, not for use against US, but to keep them from using their trusty kalashnikovs on their own citizens. You have a riot in Georgia? Send out some Spetnatz boys armed only with shovels. The result though is that the average Russian snakeeater can break bricks with his pinkie because they LIKE the hardship of constant training.
You want to assault a bridge? Get blind drunk on potato spirits the night before.
You want to build a space station? Keep a fur suit in the storage locker in case the heat goes out. (TRUE STORY, as reported in National Geographic... Russian Kosmonauts wearing fur suits to stay warm while repairing an abandoned space station, they smoked a lot during the repairs.)
You want to take a new American rifle to the range for testing, put it in a padded case and drive it to the range. You want to take a Russian rifle to the range for testing? Wrap a chain around it and drag it behind the truck to the range. (Cue Russian gun designer holding up AK-74 and smiling saying, "Yes but our rifle is also a club!")
And just to stay gun related, I really want one of those three barrelled Kosmonaut machete guns!
