Unit 112: I can not source it but as mentioned in hebrew wikipedia and as AFAIK the HAWK was retired in 2014 to allow budgeting David's Sling/Magic Wand. To be conservative David's Sling became operational in 2/2016.
I suggest adding David's Sling to the OOB in the following manner:
Unit 112 : change end date to 12/16
Create a new weapon: "Stunner SAM" as for stats I am not sure because frankly I do not know how every stat works. But:
Range should be maxed out.
Minimum range should be quite short.
The warhead is not an explosive one but very fast and meant to kill targets by directly hitting them with KE. So it should probably have high HE pen and low HE kill?
After the weapon is sorted out -
Creat a new unit "David's Sling". Start date 2/16 end date 12/25. General stats should probably be similar to Unit 112 but with better radar (because it has both a more advanced radar and an electro optic system). In slot 1 weapon should be the one we just created "Stunner SAM". HE ammo should be 12.
