The Legoland Republican Guard is the main army of the Legoland Empire. Originally an elite force dedicated to the protection of the Legoland Republic and Emperor David, the LRG emerged as the nation’s largest military wing after the 1999-2001 Treedon War.

The LRG now numbers 20 battalions totalling 500 full-time troops normally divided into 5 “army groups”; Army Group 1, Army Group 2, Army Group Centre, Army Group North, and Army Group South. In addition the LRG has 3 Motorised Divisions. The Legoland Air Corp is independent of the LRG but provides air support in LRG ground operations.
