Do both issued defensive sprays contain ultraviolet dye?

The correct answer indicates that not both issued defensive sprays contain ultraviolet dye. Typically, only specific formulations of defensive sprays are designed to include ultraviolet dye, which serves to provide a means of identification for the spray's use during an incident.

In practice, only one of the common models of defensive sprays, such as the Mk3, is known for including UV dye as a component that aids in discreet detection after deployment. This feature is not present in all issued models, including the Mk6. Consequently, selecting the answer that reflects the absence of UV dye in at least one of the models accurately represents the characteristics of the issued sprays, affirming the suggested answer that not all sprays include the dye.

Understanding the differences in formulations and components of the defensive sprays is vital for effective use and situational awareness during their deployment.
