请问line position和staff position用职场的术语怎么翻译比较好？

我在网上搜索了如下英文解释，可是不知道怎么用一个汉语术语来解释。If a company were an army, the line positions would be the soldiers on the front line fighting the daily battles and the staff positions would be the personnel off the battlefield providing support to the soldiers. Line positions directly affect the customer through manufacturing and delivering products and services. Staff positions affect customers indirectly, only to the extent that the support they provide helps line employees improve quality and customer satisfaction.
