You say "space war" and "space combat" but I see no evidence of that anywhere.
Where are the spaceship design tables or guidelines on how fronts tend to form in three-dimensional featureless space? Where are rules for vacuum or equations on laser fire at relativistic speeds?
I
do see lots of support for futuristic ground-based personal combat vs hideous aliens on exotic far-flung planets, but that's not war and combat in
space.
