I do understand that having a strong orbital defense system in EVERY planet is impossible. But at least in the key planets, including home planets, and the seats of power, they install strong planetary and orbital defenses. Going wayward, I must say that I like the prologue of the Battlestar Galactica series, where the ceylon must incapacitate the whole planetary defenses of the 12 planets in order to launch an all out planetary attack.

Short note: The Codex recognized that battles in defended mass relay positions often occurs at knife-fight range. The Codex also states that the main guns of cruisers and dreadnoughts become ineffective in close combat.Questions: why have a dreadnought defending the Citadel, which is located very close to a mass relay?
