Good system for defense

They have enough 'fodder-type' missiles/rockets to do so.

Did the anti-missile missile shot down the incoming missile with it's war head or did it shoot down the vehicle after it released the warhead?

When Iraq was firing off SCUDS and the Israelis were shooting them down with Patriots, the word was most of the hits were on the launch vehicles after they had released their payloads. The warhead is a small cool target, the missile is large and hot.

It's just one of those misinformation situations. Ooo Ooo!! we shot down a SCUD!!!!! Yeah, who cares?

Only the Scud-D has that feature. Yeman more then likely has Scud-B's.

It's a not so much that the warhead detached, but the missile broke up.

ESSAY; The Great Scud-Patriot Mystery

WASHINGTON— The Patriot missile batteries hailed as the technological star of our Persian Gulf victory -- may or may not have stopped incoming Scud warheads

A missile that is mounted on a BIG truck specifically designed to move and launch that missile?

How did they get one?

And who paid for it?

that said, I don't know if a missile was launched, if it was shot down, who fired it as I can't imagine the Southern Movement being big fans of the House of Saud and in that case than a possibility they still had them on stock from the old civil wars which the USSR was their supplier.

to Yemen.
