Imagine you being an idiot........
That's a Anti Ballistic Missile not a SAM.
It can't enage aircraft or any other fast moving targets.it can only target a steady targets.
My LIst for emergency purchases.
1)Spike LR and NLOS we can hit armor 15km away
2)Iron Dome for point defence for bases
3)ATV's for rapid mobility
4)Long Range artillery ranges upto 300km
All these can be procured in less than $2 billion dollar.
