The Clone Army at the height of the Clone Wars (then known as the HCS of course) had over 6 million men, nowadays despite having a large empire to guard the army has been reduced to just over half of that but today the Clone Defence Forces announced another half a million men are to be cut from the army as part of a 3 billion zark series of savings.
Although saving money is the primary concern the truth is that changing needs and technology such as the widespread use of drones means that the Clones need less soldiers anyway. Most of the troops to be cut will be in Category B2 and C units which guard the less strategically vital parts of the empire. No Category A units will be cut and these indeed will get a boost in increased production of new tanks.
The cuts will mean that the more minor planets in the Clone Star Empire will maintain small concentrations of troops at the capitals and key infrastructure points but most of the rest of the planets will be patrolled by drones. For example Gonas will lose 5 of the 7 infantry regiments currently based on the planet. It will retain a 4 regiment brigade (including an armoured regiment and a combined fire support / communications regiment) only though will get extra surveillance and rapid reaction assets. The cuts have already begun and will be carried out over a 2 year period.
