In 1939 when the Soviet Union invades Finland, when a Red Army division cross the border they
hear a voice beyond a hill call out:

"One Finnish soldier is better than ten Russians"

The General of the Red Army Division orders a platoon pf men to take care of the problem, shortly after a firefight, to the General's surprise, the Finn calls out yet again:

"One Finnish soldier is better than a hundred Russians"

The now infuriated General sends a Regiment of his finest men and a intense fire fight commences, the thundering sound of machine guns echo across the frozen plains and mortar grenades whistle as they strikes the enemy.

"One Finnish soldier is better than a thousand Russians" The Finnish voice calls out once again.

Enraged and blinded by his fury, the General sends the rest of his men and equipment across the fields and up the hills where the Finns were hiding, concentrated artillery bombards were ordered, waves of tanks forming the roaring armored spearhead, backed up by the toughest of infantry with the best pilots of the soviet air force supporting them from above. The most intense skirmish seen on earth had taken place.

After the gunshots end and the last tanks blown up, one man, heavily wounded crawls back to the general and says:

Don't send any more men... it's a trap. There's two of them.
