Were you asking how the 36th Georgia arrived in Mississippi prior to the Vicksburg Campaign? I'm assuming you know about the campaigns of this regiment in East Tennessee and Kentucky during 1862.
You asked about 'basic' training.
Officers often assumed that soldiers knew basic military drill from civilian life when nearly every adult male attended regular militia assemblies. Pressing needs to be addressed involved regimental organization, such as election of officers, appointment of field and staff, requisition of basic supplies, equipment and transportation necessary for field operations. If available (and often they were not), arms, ammunition and accoutrements were issued during this time. While waiting for the regiment to receive wagons, cooking utensils (try living in the field without those!), blankets, tents, proper forms for pay, muster rolls, requisitions and receipts, company and battalion drill occupied much of the men's time.
