Why do snipers in "All-Out Warfare" mode get low scores? Why do they even get military merit points deducted?

Snipers—an important role in reality—but in Delta Force, when you painstakingly use a sniper rifle to take down enemy snipers or assault troops, your score is ridiculously low. Does this mean snipers are useless? We can't look at things one-sidedly. Countering snipers is highly rewarding, yet the score is low. What's the point of using sniper rifles in this mode if this continues unchanged? You work hard all game only to have your merits reduced—can't you not be angry in this situation? Hopefully, the developers will fix this as soon as possible.
