Soldiers writing from the front.
In the wars of Israel, the IDF made sure to allow soldiers at the front to write home, and gave soldiers different postcards that enabled them to smile and write home a few words.
And envelopes. Usually, the number of postcards was limited. Only in the Yom Kippur War of 1973 were dozens of models of postcards sent to the front in packages of battle rations. The soldiers returned the postcards with every vehicle that returned to the rear, and especially helicopters that returned the wounded. The main postcards were prepared by:

1) Post office with postal symbol and symbol (4 different).

2) Government ministries.

3) The IDF by a Chief Education Officer.

4) The management of Shikam.

5) The Committee for the Soldier.

6) Private companies that printed the postcards and submitted them to the Committee for the Soldier.
The postcards that reached the military bases received the stamp of the triangle, some only the censor's stamp. In the first combat battalions, the postcards were thrown into the civilian mailboxes and distributed to the homes by volunteer youth, and some of these postcards were issued without a stamp
