Throughout the years, generated obscuration has been a staple of the Chemical Corps.
The Army maintains some obscuration vehicles--most of which are included in pre-positioned stock or in reserve within the continental United States, rather than in use by a deployable unit.
There are a few uses of generated obscuration in counterinsurgency-focused operating environments.
Obscuration was one of the capabilities that went by the wayside in favor of other capabilities that better met the immediate needs of the Army, such as CBRN reconnaissance and homemade-explosive laboratory exploitation capabilities.
A common argument for the phasing-out of vehicle-based obscuration was that artillery is a cheaper and easier means of employing obscuration.
Today, obscuration operations carry the same stigma as other outdated weapons of the past such as horses and spears--both of which met their ends due to the steady advance of technology.
Obscuration serves as one of the most effective means of denying multispectral targeting by the enemy; graphite-infused smoke is one type of widely available obscurant used for that purpose.
While Army obscuration capabilities were undergoing reductions, funding was approved for the development of replacement equipment to fill the capability gap.
There are some advantages to artillery-delivered obscuration over vehicle-mounted obscuration; however, artillery rounds do not measure up to a platoon of M58 smoke carriers on many levels of practical implementation.
In addition to the aforementioned benefits of obscurants, obscuration can also be used in support of breaching operations.
