When Viktor Suvorov was beginning his military service, he was taught to count every round:
Cartridges are metal and a lot of hard work. It is more difficult and more expensive to make a cartridge than to make a fountain pen. And another reason for being careful with ammunition is so that you are never without it at a critical moment. Supplying an army with ammunition is a complex logistical problem. If the transport carrying ammunition arrives even a few minutes after you have spent all your ammunition without thinking, then you are dead. But there are no such problems in Beirut. Nobody tells the conflicting groups what the ammunition costs. Nobody tells them the cost of the lives they cut off every day. Nobody mentions the danger that the regular supply of ammunition may be late. The suppliers are certain that it will not be late.
The Soviet Union condemns the civil war in the Lebanon. But there is no need for it to condemn the war. All it has to do is hold back the next transport of ammunition, and war will cease.
