When our allies and friends provided us with M777 howitzers, we were thrilled.
These are arguably the best and most reliable howitzers in the world. The 155mm caliber does its job on the battlefield, and they shoot very accurately, especially with Excalibur shells, which can exceed a range of 40 km.
They also gave us powders that are stored in such airtight iron tubes. They are of high quality and beautiful.
And you can create beautiful things in the Art of War style with them, which you will definitely like.
