The Magach 3 was an overall upgrade to the M48 tanks fitted by Israel. Compared to the Magach 1 and 2, it was the first to receive major upgrades not fitted by Americans or Germans. It included a more powerful American-made 105 mm M68 cannon with more powerful anti-tank rounds to deal with Soviet threats like the T-54 and T-62. The tank also eventually received Blazer ERA to deal with Soviet made RPGs and ATGMs fitted in large quantities by Egyptian and Syrian forces. The tank also received a new 750 HP engine coupled with a new Allison transmission (the same used by the first M60s), as well as new radio equipment and electronics.

It was introduced in Update "Drone Age". The Magach 3 is an upgunned version of the previous Magach variants. It has very similar mobility thanks to the new transmission and engine. However it does not use Blazer ERA blocks, since that is reserved for the premium version. The 105 mm gun with its new APDS shell is the most important upgrade as well as the new commander's cupola. The new gun packs quite a heavy punch and can be used to reliably penetrate all tanks at its BR, that being with the HEAT-FS or the APDS shell, just take in mind that ERA can already be seen around its BR which poses a threat to chemical munitions. The tank lacks a stabilizer, however, it has an optical rangefinder so it can be used to accurately pick targets thousands of metres away.
