The use of modular tactical load bearing belts has consistently grown in the past decade. The influence of special operations in tactical training and shooting techniques has brought a very versatile tool in the hands of many users. What is typically referred to as “first line” is, in fact, the primary layer on top of which the users equips himself. This terminology has been applied to professions in which there is a multi-level approach to equipment. In almost all cases the first line is the first to be applied before heading out of the door and the last to be taken off. Different professions require a multi line system for different purposes: Law Enforcement usually add a second-line (chest rig/PC) for special purposes while using the first line (belt) as the main source, on the other hand we usually see the opposite with military applications, in which the belt mounted equipment is a backup for the plate carrier. There are exceptions to this in both professions, for example we see often the positioning of the magazine designated for speed/emergency reloads placed on the belt at the 9 o’clock.
