The 74th Imperial Garrison represented a military force dispatched by the Galactic Empire to the Outer Rim Territories. Before the Battle of the Gauntlet took place in 0 ABY, the Garrison experienced an attack, a raid, conducted by the Rebel Alliance, leading to the pilfering of multiple prefabricated structures.
The Fantasy Flight Games adventure, Onslaught at Arda I, a roleplaying game released in 2014, included a reference to the 74th Imperial Garrison.
