The western alliance is not the only one providing military training. Iran has sent military members to Crimea to train Russian troops. Specifically, they are training them to use Iranian drones. There were reports of Russian troops visiting Iran in August to learn how to operate unmanned aerial vehicles (UAVs). Since then, there have been numerous reports of UAVs failing, but the successfully deployed UAVs are capable of causing serious damage.
Shaheds, also known as kamikaze or suicide drones, explode on impact and are capable of also carrying missiles. This drone is less expensive to develop, but it can travel up to 1,000 miles and leave a range of destruction in its path. Mohajer-6 UAVs can be used for spying purposes and can, of course, also hold a missile. Ukraine claims that they have shot down at least 200 drones and have the capability to jam radars.
Both Russia and Iran have denied trading weapons, but what do they have to lose now that all the cards are on the table? Russia has violated the UN Security Council Resolution 2231 by transferring arms from Iran. The West has already sanctioned Russia in every way possible. Numerous nations are placing sanctions on Iran now, but again, they are not too concerned. Tehran and Moscow, two nuclear powers, are strengthening their relationship and seem prepared to face any Western consequences while resuming trade.
