Hi Honu,Gan addressed most of my style concerns, so I only have a few suggestions.
"The warm glow from Old Beastie was felt by all of us in Air Marshall (AM) Takahashi's office."
A warm glow filling the office is sufficient for me. I don't get the passive "felt by all of us" bit.
"He told me that I was at a disadvantage. He was probably right. He was some kind of master in Okinawan Karate. Even though I was twenty years younger, sixty pounds heavier, and had a foot of height on him, he'd made short work of me."
Something like "He revealed his advantage. He was a master..."
is more direct.
"I got up to pour myself another scotch, again noticing the ancient blaster and wicked looking pig-sticker of a serrated sword hanging over the cold chest where the scotch was kept."
More direct: "I poured myself..." "...where he kept the scotch."
“Sir, if I may ask, what's the story of these weapons?”
The AM looked at me a little blurry-eyed. For a minute I thought he wasn't going to answer, then he spoke very quietly."
Do you really need "little" or "very?"
Interesting atmosphere. Good luck with it.
Cordially,
Ron
