Israeli M339 is an HE-TF round with a delayed fuse intended to punch through buildings and fortifications like SAPHE. Not only that, but it’s also one of the most fun shells in the game, so why must we have another fun aspect taken from us?
In the last 3 months, Israel’s Merkavas have lost their engine armor, roof armor, and now their HE-TF penetration.
But considering that 155mm M107 shells have 2.5 times that TNT equivalent and have less HE pen, the 120mm shell was overperforming by A LOT to begin with, so it’s more of a return to normal rather than an actual nerf
It’s HE-TF with abnormally high KE penetration, but it before the Auto-tracking buff, the fuse could be used to detonate the shell after penetrating certain areas (roadwheels, weak hull sides, driver ports etc), allowing it to kill much more effectively than a typical HE or HE-FS shell.
The ability to do so was nerfed about a year ago, this further nerf just makes it a weaker 3OF26 essentially
This web page details a lot information about M339, which in-game is not correctly represented if the information containing in this website is true (from HE-TF in-game to HE-MP-T), although not correctly, I see this to balance or put in par to other large caliber HE-TF projectiles, take 3OF26 EDKV as example.
