No worries at all. Yes it is. I thought it was challenging to get its shape to look right. But an enjoyable icon to create.

No, I used a drawing and photos out of the book Firepower. But that looks really good too. Only differences are the locations of the moveable cranes. This particular drawing has them both mounted in their front positions. Mine had them mounted on their right side positions. They were designed to be repositioned around the vehicle as needed, when working on the outer set of tracks. They are removable and can be towed behind the vehicle for transportation or bridge crossings, etc.
