I don’t think rpgs bothered US tanks much in Iraq

US never used armour like this. They deployed infantry to this kind of thing. Look at the battle of Fallujah for the closest time the US has been in this kind of thick combat, all infantry fighting with light vehicle support. Heavy armour stayed in distant support and diversionary roles. Never presenting side/rear armour to enemies, this is the major factor really, tanks are designed to be hit from the front, they really not armoured for direct hits from anti tank weapons to the sides, top and rear.

Also the RPGs are not the same. Although similar. I get the impression the Yasin performs slightly better than the RPG7.
