Everyone but not mechanical engineers think better than mechanical engineering to produce this type! Stupidly manually loading, too many men but shots token long minutes per one shot.
Apart from the automatic loading device, I think this is a very good feature that allows the soldiers to manually load bullets in the event that the automatic loading device malfunctions.
This is a completely failed design in Japan. It cannot rotate left and right and is manually loaded. The bloated vehicle design will make the passability poor. This kind of semi-finished product should not be produced. Instead, it stays in the laboratory and is a complete failure.
