You can PCS in the army every 2 to 4 years. In case you are expecting a PCS order, it is best to be prepared beforehand, and to do that, give away things or put products for sale and start planning everything early so that you do not feel overwhelmed by the sudden order. Do not forget to inform the landlord or property owner too or the government quarters or temporary quarters you live in. Avoid damage to your property during movement.
