I need more information on what you mean by “full swing”.
If you mean a golf swing, it depends on your level of skill and the type of club you are using. A beginner can expect to pay around $50 for a set of clubs, while a more experienced golfer may spend upwards of $1,000.
If you mean a full-blown attack, it can cost a lot of money. For example, a full-scale military operation can cost billions of dollars.
