The "Scout Fleet" Assault on Babylon 5 occurred after the Second Shadow War and Sheridan's Campaign to liberate Earth. An alien race of unknown origin traversed through known space, attacking selected targets to test their defenses to ascertain whether or not it was worth conquest.
Ships belonging to this species destroyed long range probes sent out into hyperspace by Babylon 5. Afterward, an initial wave of ships traveled through the jumpgate and attacked Babylon 5. Later, the species arrived with their main fleet, attacking the station with cruisers and fighters which were able to damage B5's hull with a few hits. Breaching pods allowed soldiers wearing suits of armor that covered their entire bodies to penetrate and attack the station's lower levels. All invading ships were eventually destroyed.
