Self-Propelled Guns. Part-Two.

Anti-Aircraft.

With the advent of the missile one would think that the days of anti-aircraft guns have come to an end, but you would be wrong. Every day and night our 24/7 media portrays militants around the world converting Toyota 4X4's for this purpose along with various types of trucks.

Guns from heavy machines U.S. and Russian 12.7, 14.5mm to small cannons of Swiss Oerlikon 20, former Soviet 23mm are used in general clashes. meanwhile bigger cannons are recovered from defunct military vehicles such as in the 30mm calibre.

Despite this many countries still have mobile anti-aircraft guns such as the Russian/Chinese built ZSU-23 quad 4X23mm and various takes on the 30mm rotary cannon and most successful Swedish Bofors 40mm.

All these weapon systems now make helicopters venerable to ground fire more than aircraft, unless they are coming into land or taking off.

Terrorism. Part-One.

Improvisation.

Terrorists usually operate with light arms, RPG's (Rocket Propelled Grenade Launchers), SAM's (Surface to Air Missiles) and occasional Cannons up to 23mm calibre. But some are more than a small group and could be described as a little army. 

ISIS/ISIL Now come into to join the PLO, Hezbollah, FARC and the Al-Quida/Mujaheddin-Taliban.

Many of these groups have commandeered existing occupation military equipment and have adapted it to suit their own environments such as Libya, Somalia and Iraq/Syria. From Toyota pickups to heavy armour are being converted or worked down, rather than reinforced.
