The idea that a unit would like to use Precision , semi-guided , Homing , ARRAD or other non - Standard ammo and cannot ever reasonably get it from the Client's logistical train might actually commission a ammo manufacturer to make it for the unit directly . The down side is the retooling and associated costs for doing so would be demand a certain minimum lots size during any quarter in which it was made . So what do you think the lot size should be ? And how much over your own unit's needs is it if any ? Say a Small Factory making 1,200 tons of high tech ammo a year so the minimum lot size to buy is 300 tons in a quarter . A Large factory would be 3X more . Not a big issue for my unit now but when it was much smaller depending on the Client ammo shortages happened from time to time . In a strategic game the unit may very well buy in , build , or steal the factories to guarantee the ammo flow required will be available .
