What is Iran's reasoning for this?

Iran has signed a huge deal with Russia, only hours after they signed the peace deal with America. And today, one of Iran's top officials visited Russia and met with the head of Russia's state helicopter development company. And in the meetings, Iran agreed to buy 20 Russian military helicopters. Iran said, "Today an agreement was signed for the direct purchase of 20 helicopters from Russia, aimed at strengthening our country's logistics and aerial rescue fleet." Iran described this move as "an unprecedented milestone." Some people are saying that Iran is already preparing for the watery start by them doing this, because the peace deal came hours ago. To be fair, there is still a 13% chance that the US will invade Iran by the end of the year. That is, despite the fact they've now signed a peace deal. That's according to Polymarket, by the way, a place where you can predict world events. But these are not just normal helicopters, they are military-capable ones. Iran said quits, "These helicopters are equipped with modern technology and night vision systems, enabling night flight operations." Iran famously has never had night vision on their helicopters, which many times have resulted in helicopters crashing at night time. I will say, I don't think Iran is buying these helicopters to prepare for a war. 20 helicopters wouldn't do that anyway. I think Iran is replenishing what was lost during the war. Many Iranian helicopters were destroyed by the American and Israeli strikes, and Iran needs to replace them, and they're replacing them with better versions, it seems. Iran also said the helicopters will be used for search and rescue missions and fighting wildfires in the future. But there is something I haven't told you yet.
