Isonzo

I recommend attempting this achievement on a fresh server, so from the main menu press RB so you're in the 'Play' menu. From here press Y to create a Custom Match, turn on the Friends Only setting, and choose the 6th Battle of the Isonzo Offensive starting on the Carso map (This works on any map, but I found this one to be easier).

When you get into the lobby choose to side with the Kingdom of Italy so you're attacking. If you start as the Austro-Hungarian Empire, you can click the leftmost Emblem from the spawn screen to switch teams.



Spawn in as any class on the leftmost point so you can help push to the Forward Camp in front of you. If you're yet to get the Avanti Savoia! achievement, being the one to build the Forward Camp will unlock it for you. You'll notice that the two objectives have different icons. A has a flag icon, which shows that it's an area capture objective, while B has a dynamite detonator icon, which shows that it has something you need to destroy. Make your way into B, the AI shouldn't give you much trouble, and head to the makeshift command centre there. Hold X to plant the dynamite and defend the area from the enemy bots that want to disarm it. The planted dynamite with have a red triangle around it; you want to be standing in an area that has the red triangle and also says 'Danger Close!'

Once the objective goes boom and you're sufficiently dead, the achievement should pop! 💀🐺
