My Respected Arab brother, Asalam-O-Alikum.
Bro. actually KSA should be a power house not just a country map in the world. So it needs to have a robust Military although it is moving slowly forward but the speed and the pace is not good at all.
I would recommend that KSA should start working from today on making a Regular Army of 700,000 Men and about 110,000 men as SSG(Army). Regular Army men would be guarding the borders of KSA in all of the North-South-East and West in an 8 hour shift of about 70,000 men.
More over, KSA needs to have a good airforce and navy as well especially a bigger submarine force.
Bro. UAE, Jordan, Oman and Yemen all of them needs to work more and more on their Military to grow in numbers, equipment and especially technology. Not to Forget Bahrain, Qatar and Kuwait must also not forget it.
