What is generally the characteristic of a light mortar in terms of mobility?

A light mortar is designed to be lightweight and easily portable, allowing for greater maneuverability and flexibility on the battlefield. This characteristic enables troops to quickly move the mortar to various positions as needed, enhancing their ability to respond to changing combat conditions. The emphasis on portability helps ensure that the unit can transport the weapon system without significant logistical challenges, which is particularly important for infantry units that must maintain mobility while remaining effective in providing indirect fire support.

In contrast, characteristics such as being heavy and difficult to transport, moderately heavy but still requiring some effort to move, or very heavy and stationary are not associated with light mortars. These traits would limit the operational effectiveness and strategic deployment of the weapon system, making it less suitable for the dynamic environment in which light mortars are typically employed.
