1) Tunisia is NOT POOR, Tunisia has its ways of getting the most advanced weapons with the minimum budget due to its great Military relations with the United States, Tunisia's Ally, and The European Union.

So Money is not a "constraint" anymore.

2) Tunisia has NO MILITARY RELATIONS whatsoever with the Russian Federation, meaning it's almost impossible to change providers.

3) Tunisia has NO INTEREST of adding Soviet-Russian Equipment in its inventory for a simple reason that guys in the Ministry of Defense knows best: useless waste time to Train on another platform of weapons, security problems related with Russian equipment, low technology and incompatibility with the doctrine of the Tunisian Armed Forces.

so to conclude, stop saying "let's buy Russian weapons they are alot cheaper because you'll simply make of yourself a fool".
