Final answer:
Green blast doors on a TASER cartridge signify it contains 25 ft of wire and an extended probe needle, suitable for long-range engagement and penetration through thick clothing.
Step-by-step explanation:
The green blast doors on a TASER cartridge indicate that the cartridge is equipped with 25 ft of wire and an extended probe needle. This configuration allows for a subject to be targeted from a greater distance compared to the standard 15 or 21-foot cartridges, which are typically used for closer engagements. Extended probe needles are designed to better penetrate thicker clothing, which can be particularly useful in situations where the subject is wearing heavy layers. The length of the wire is crucial, as it determines the maximum range at which the TASER can be effectively used.
