When referring to a vehicle or structure, saying that it is equipped with an antimissile system (AMS) means that it has an advanced defense mechanism against incoming enemy missiles or projectiles. However, there are several synonyms that can be used to describe the same thing. For example, the vehicle or structure could be said to be armed with an AMS, outfitted with an AMS, installed with an AMS, or even fortified with an AMS. All of these phrases convey the same message - that this particular target is well-protected against missile attacks, and has taken the necessary precautions to ensure its safety.
