Primaris air defence missiles

This ability always takes the form **[ANTI-X Y+]**. Each time an attack is made with an **[ANTI]** weapon, if the target unit has the keyword denoted by **X**, an unmodified **wound roll** of **Y+** is a **critical wound**.
***Example:** An attack made with an **[ANTI-VEHICLE 4+]** weapon against a ^^**Vehicle**^^ unit will result in a **critical wound** on an unmodified **wound roll** of 4+, while an attack made with an **[ANTI-PSYKER 2+]** weapon against a ^^**Psyker**^^ unit will result in a **critical wound** on an unmodified **wound roll** of 2+.*
