#Tunguska AD
I love Air defense systems,
In my beginnings, I started to read about #Egypt modern wars, then I realized through my readings that our AD was one the biggest reasons of our victory in October 1973 war, at that time,

1/12 I noticed that the AD in October war suffered from few issues like :

1- Most of our AD weapons were stationed like SA-2 & SA-3.

2- Only the SA-6 radar & launchers were tank tread vehicles & the other units like transloader, crane, P-15,
