Hadre-Karida Plan

The is a incredibly popular UNSC military tactic that forms the basis of all UNSC offensive and defensive operations. The plan was formed between 2559 and 2563 by military tacticians Lieutenant General Ernst Hadre and Rear Admiral Steffan Karida. The plan was a simple, Sun Tzu style policy, in that 'he who defends everything, defends nothing'. Though the plan was high risk, the idea was simple. Enlargen the existing UNSC sectors and increase the numbers, each encompassing around 10 colonies. At each 'Command Centre' several fleets would be positioned with attached Marine divisions, regiments and expeditionary forces, marine air forces and a number of UNSC special forces. Due to the new high speeds capable of UNSC ships, movement around colonies could increase exponetially, allowing fleets and troops to arrive at combat zones as soon as Brute forces arrive. Thanks to advance arrays of slipspace detection stations stationed in every colonised sector and the new highspeed Slipspace Optical Communication Arrays which allowed near instant communication between colonies planets could be alarmed about incoming forces days before their arrival and alarm UNSC forces as soon as enemy forces are discovered. This meant uNSC forces could arrive anywhere between a day before or a day after the arrival of enemy forces, allowing them to leap to the defence of thier world. 'High Risk' worlds would also possess a garisson and a number of battlegroups themselves. This would allow these worlds to 'hold until relieved' and enemy forces would be crushed by sheer weight of numbers.

Though the Hadre-Karida Plan came under heavy fire during its inception, in 2580, with the resurgence of the Covenant Remnant, the plan was hailed as a brilliant tactic, allowing the UNSC to deftly defend those worlds coming under attack. However, the plan had difficulty in adapting to the sheer power of the Necros War war machine and by the time they had adapted the plan the forward FLEETCOM sector had already been swallowed by the Necros warmachine into what became known as the Gundark pocket. A small stretch of space about three sectors in size, with the FLEETCOM sector 13 command centre, Gundark, trapped at the centre, along with six UNSC fleets, a Marine Army Group and around 700 million civillians.
