From the article:
Searchlights patrol the night sky, seeking signs of the enemy amongst the shifting landscape of war. For such a task, the LAAT/le Patrol Transport is the oft-utilized asset of the Galactic Republic, and later the forces of the Empire, when tracking down and apprehending priority targets. On the battlefield, these nimble transports are used to rapidly deploy troops where they are needed the most, regardless of impeding terrain or hostile environments. Able to soar over obstacles, the LAAT/le can quickly get your troops where they are needed most, and once there, protect their position with aerial support.
