The Saudi military is almost entirely staffed by mercenaries. The Saudi jets bombing an air defenseless Yemen are piloted by Pakistanis. Its mid and low level officers are mainly from Jordan and most ominously for its ability to actually launch a ground invasion, its rank and file soldiers are almost entirely from Yemen.
That’s right, the Saudi army is packed full of Yemeni cannon fodder, which helps explains its ignominious failure in its war with Yemen’s Houthi’s in 2009.
Does anyone really believe that the Yemeni soldiers for hire in the Saudi army are going to willingly, never mind effectively, invade their own country, leaving a trail of destruction in their wake all the while killing, and being killed by, their Yemeni brothers and sisters?
This may explain the reluctance of the Saudi leadership to launch their promised invasion, especially while the Houthi militia’s are still an effective fighting force on the ground.
Supposedly Egypt is going to send its army to help invade Yemen, never mind Yemen being the graveyard for thousands of Egyptian soldiers in what the late President Nasser called Egypt’s Vietnam in the early-mid 1960’s.
The Egyptian army is made up of mostly illiterate conscripts dragooned from the poorest sectors of Egyptian society and has been particularly inept at suppressing the vicious insurgency being waged again President Al Sisi’s regime in the Sinai. If the Egyptian army cant even control its own territory it certainly doesn’t bode well for any foreign misadventures it may undertake.
