Another way you can help IDF soldiersthis.
Hebrew word "shmira" (pronounced shmeerah) means "guarding" or "protecting". In modern Hebrew, shmira also means guard duty. The Shmira Project is an ongoing, grassroots program that pairs IDF combat soldiers with Jews around the world who do acts of kindness, prayer or Torah learning to increase the soldier’s spiritual merit and protection.
The Shmira Project is a person to person match that everyone can do. It follows the ancient practice of pairing physical effort with spiritual effort. The families of soldiers and the soldiers themselves enjoy the reassurance of spiritual support. Participants enjoy knowing that they bring about unity and connectedness. There are absolutely no fees.
This project originated with Rav Simcha HaCohen Kook, Chief Rabbi Rechovot & The Hurva Synagogue with the Bostoner Rebbe, zt”l in 2009 during the Gaza Operation Cast Lead. It has the support of people across the world and across all denominations. It's being organized in its present format by the mother of a former IDF paratrooper. Rabbinical Endorsements - הסכמות
