An Anachronism

In Poul Anderson's "Cold Victory," the Humanists have pulled Earth and Luna out of the Solar Union so Mars and Venus help the anti-Humanist counterrevolutionaries. Thus, the Unionist space navy comprises Martians, Venerians and Earthmen. Robert Crane from Earth leads a small team consisting of himself, the Venusian Garcia, with clan markings on his spacesuit, and the Martian Wolf:

"They were an anachronism, thought Crane, a resurrection from old days when war was a wilder business. The psychotechs had not picked a team for compatibility, nor welded them into an unbreakable brotherhood. They had merely grabbed the first three willing to try an untested scheme. There wasn't time for anything else."
-"Cold Victory," p. 59.

This whole war sounds like an anachronism to me. I think that there is even mention of booty although I will confirm or disconfirm this as I reread. What is interesting is that "psychotechs" are mentioned. Even though psychotechnic policies have been banned and the Institute outlawed on Earth, a science, once learned, is not forgotten.
