Could Scotty still give orders in Relics?

[Maurice]

Based on real world armed forces with ranks and all that, could Scotty immediately give orders in Relics after presumedly being considered dead for almost eight decades?

Discussed above I'm sure, but succinctly: No.

1. He's retired.
2. He's not part of the Enterprise's chain of command.

1. He's retired.

Not to mention presumed dead.

HIST 2927 - Kirk's Five-Year Mission - An Eyewitness Account

ENGN 1446 - 23rd Century Warp Engine Design

TEMP 1872 - Everyday Life in the 20th Century

Apologies but this post deeply confuses me. Since Kirk's mission wasnt in 2927 and 1446 and 1872 are not 23rd or 20th centuries I'm obviously missing something.
