The Syrian armed forces have upgraded its combat vehicles with a local-made
armor cage, to increase protection against anti-tank-missile and RPG (Rocket
Propelled Grenade) – a Syrian style "Trophy" system.

The website ARMY RECOGNITION reports that many pictures are published on the
Internet showing Syrian army T-72 main battle tanks fitted with armor cage,
as well as the the ZSU-23-4 Shilka anti-aircraft gun.

According some military sources, the combat vehicles have been upgraded to
be protected during urban combat operations. The hull of the Syrian ZSU-23-4
self-propelled anti-aircraft gun is covered at the front, rear and on each
side with an armor cage which seems to be designed and fitted locally. The
lower part of this armor is fitted with closely spaced chains with ball
ends.
