"This forced us to take an adequate response aimed at improving the security of Russian troops performing tasks to combat global terrorism in Syria", he said at the briefing in Moscow on Monday.
A number of Israeli media outlets have expressed concerns over Moscow's decision to supply Syria with S-300 air defense systems and admitted that such steps may have grave repercussions for the Israeli Air Force.
In remarks quoted by Russian news agency Interfax, Mr Shoigu said the delivery of the system had been suspended in 2013 following a request from Israel, but added: "Now, the situation has changed". Russian Federation will also jam the electronic communications of aircraft attacking targets in Syria, he said.
"We are certain that the realisation of these measures will cool the "hot heads" and will keep them from poorly thought-out actions which threaten our servicemen", Shoigu said.
"Unfortunately, the Russians have stated their intention to introduce very sophisticated anti-aircraft systems into Syria, give it to the Syrian army".
Shoigu said Russia will equip Syrian anti-aircraft units with Russian tracking and guidance systems in order to identify Russian aircraft.
The Syrian Observatory for Human Rights, a Britain-based war monitor, said the forces deployed to several Turkish positions around the northwestern province. However, officials in both Israel and the United States warned Russian Federation against providing the Syrian military with the advanced surface-to-air missiles, saying the transfer would further destabilize the region. The S-300 is a development of the S-75 missile that famously shot down the U-2 spy plane over Russian Federation in 1960, during the Cold War.
Israel's use of long-range standoff weapons, which allow jets to strike targets without needing to necessarily enter Syria's airspace, is also an important ability.
Russian President Vladimir Putin told Israeli Prime Minister Benjamin Netanyahu on Monday that he disagreed with the Israeli version of events concerning the downing of a Russian plane over Syria last week, the Kremlin said.
But he also repeated Moscow's accusations that Israel was to blame for the crash: "No doubt that according to our military experts, deliberate action by Israeli pilots was the reason for the tragedy and this can not but harm our (Russia-Israeli) ties".
Speaking at a briefing at the start of the assembly, Le Drian said: "It is the responsibility of the president of Syria Bashar al-Assad but also those that support him to to seek a political solution".
It seems clear however, that for Russian Federation, the transfer of the S-300 at this stage of the Syrian conflict is to save face.
"Right now our troops inside Syria are there for one objective, and that's under the United Nations authorization about defeating ISIS", Mattis said, using another acronym for Daesh.
