Bro, when you are less in numbers, you need to stick to using more advanced weapons and strategies, look at Israel and how they defeated much bigger arab armies. Your air force is already enough to deter them, but it is not as strong to give you the upper hand. in land forces, Iran can outnumber turkmens, simply because they have more soldiers, so your option against them is having more weapons, like more tanks, ... Also, consider that Uzbekistan has not a strong economy and Iran is in embargo of buying weapons. So, you need to use this advantage and buy more modern stuff compared to them. about this neutral thing, it is officially what Ashgabat is saying but in reality, they are in favor of Russia. Anyway, I doubt if ay serious was happens for turkmenistan, since all the countries of that region, Turkmenistan, Kazakhstan, Uzbekistan and Iran are in the same pack, aka Russian pack. About Ashgabat border with Iran and also your border with Afghanistan, you do need to use mine fields and such stuff, but, for other borders, I don't see the necessity to do so
