Usually, they would first deploy teams equipped with anti-tank guided missiles (ATGMs)—like Russian made 9M113 Konkurs, 9M113 Kornet-Es and a few BGM-71 TOWs—to take out specific vehicles or bunkers.

Meanwhile, pro-Houthi special forces would start assaulting the border outposts, while motorcycle mounted teams armed with RPG-7s and US-made M47 Dragons would infiltrate into the Saudi rear.

Columns of Saudi Arabian Army (RSLF) forces would thus drive into unknown minefields, or rush into ambushes at places not directly hit by the fighting.

Some raiding parties deployed into Saudi Arabia were armed with man-portable air defence systems (MANPADS), as well as M167 Vulcan towed anti-aircraft cannons.

The Saudi authorities temporarily closed local educational institutions and the Najran Domestic Airport.
