Obscurants
Obscurants refer to substances or materials that are used to obscure, conceal, or block vision. These materials are typically deployed in military operations to create smoke screens or to obscure the visibility of enemy forces. Obscurants can also be used in riot control situations or for industrial purposes such as reducing visibility in certain environments. These materials work by scattering or absorbing light, making it difficult for individuals to see clearly through the obscured area.
