January of 1968.
Egypt, which was defeated in the Six-Day War with Israel, is rebuilding its army.
A tender has been announced for the purchase of military field radio stations.
Since Egypt itself did not issue such radio stations, invitations to participate in the tender were sent to the world's largest producers, and, of course, to the Ministry of Defense of the USSR, which supplied Egypt with the lion's share of weapons.

At a military base on the edge of the Libyan desert, under the tables, potential sellers exhibited their products. American Motorola, Dutch Philips, German Siemens, Grundig, Telefunken, Japanese Sharp, Panasonic, Technics... Everyone shines with chromium moldings and nickeled bulbs, blinking with yellow, red and green bulbs. Among them, the alien will stand out the Soviet radio station - a metal parallel piped, painted in the color of the hack. It was the R-107M.

A tender committee – a dozen roasted Arabs in military uniform – willingly spends time between the tables, considering the presented equipment. Here they are like enchanted frozen in front of the Japanese stand. It was colour music. The military representative of Foreign Special Export did not stand, approached the Arabs, spoke to them in English. Those in accordance left their heads, began to give commands to the officers at the base.
The soldiers transferred the radio stations to the runway, putting them in three rows.

The Soviet officer took the grenade brought to him and threw it into the middle of the exhibition.
From the explosion radio stations flew on concrete.

To the surprising expressions of the persons of the sellers and buyers, Major Ivanov answered briefly:
Now compare it.

The Arabs chose the Soviet radio station.
The only one who worked.
