GAZZE test of the Israeli Army's Merkava tanks

The bubble around the Merkava tanks, which for years had been mythologised as invulnerable and which Israel was said not to sell to anyone lest the technology unravel, burst when several tanks were destroyed by Hezbollah in Lebanon in 2006. However, Israel immediately started working to protect its tanks against anti-tank weapons.
The improvements made to the Merkava seemed to be working until 7 October. Because Merkava tanks were not destroyed in the clashes, at least the tank crew survived the attacks unharmed. However, this situation changed in the clashes following the attack by HAMAS on 7 October.
In the first two months of the clashes, at least 20 Merkava tanks were destroyed. Moreover, these tanks were hit by Hamas fighters who did not have advanced laser-guided anti-tank missiles or even the previous generation of wire-guided anti-tank weapons.
One of the causes of these casualties was the Al-Yasin anti-tank weapon. The Al-Yasin is not even a weapon. It is the name of a Hamas-made munition attached to conventional kinetic energy RPG rockets. There have been many comments about this ammunition, which has a two-stage spelling on it. There was a lot of discussion about how such a simple and handmade ammunition could overcome an advanced active and passive protection system such as the Merkava and hit the tank. 
According to the video footage, the success of this ammunition is due to the fact that it is fired at very close range. This ammunition is fired so close to the tanks entering the built-up area that it can reach and hit the tank until the active and passive defence systems on the tank detect the ammunition.
Although this situation is much talked about, Merkava tanks were not destroyed only with this ammunition. There are also tanks that have been destroyed with a very simple and cheap tool, drones used for civilian purposes. In October, for example, footage was released of a small Hamas drone with explosives on board neutralising a $4 million Merkava. This once again raised questions about the effectiveness of main battle tanks in general and Merkava tanks in particular. Moreover, the Israelis have installed steel cages on their tanks to protect against such attacks, but to no avail. 
However, not everyone accepted that the tanks were inadequate. Some attributed the casualties to crew incompetence rather than tank incompetence. According to them, at the time of the attack, Israel's tanks were understaffed. Although the Merkava 4 tank had a crew of four, it was claimed that there were two crew members in each tank. 
On the other hand, there are those who try to minimise and downplay the tank casualties. According to them, although rocket launchers are good at disabling tanks, they do not have enough explosive power to completely destroy a Merkava. However, there is one point they overlook. Even if the tanks are not completely destroyed, the fact that they remain out of action is a significant enough achievement. 
Indeed, since the beginning of the war, the Israeli army has made great efforts to minimise tank casualties. For example, it does not allow tanks to enter residential neighbourhoods alone unless they are protected from a certain distance by sufficient infantry. As far as possible, it does not allow tanks into narrow streets. It does not enter an area until it has completely devastated it by air and ground bombardment. These measures seem to have partially worked. As a matter of fact, the initial large tank losses are no longer occurring.
