▃▃▃	Installation

Most formations of battalion level or higher integrate auxilary forces beyond the basic structure. In a standard SLDF mech regiment, for example, each battalion has an additional command lance not counted as part of any specific company, and a regimental command lance not counted as part of any battalion, so the regiment has 124 mechs rather than the 108 in a nominal regiment. They also include an air lance attached to each company, giving it a wing of 18 aerospace fighters as well. They also include technicians, recovery vehicles, transports, medical and administrative personnel, and other support elements, generally outnumbering the actual combat elements.

Infantry formations can be wildly variable in size. Jump infantry platoons typically have three squads while foot and motorized platoons have four squads. Most infantry squads have seven troopers, but SRM squads have only six. This means that "standard" infantry platoon size might be 18, 21, 24, or 28 troopers, and so a standard 27-platoon infantry regiment might be anywhere from 486 to 756 troops, not counting any attached command or support elements.
