Engineerfag here. My first attempt to post was not successful. That projectile was not a round from a railgun or any EM device. It’s a missile. Earlier an anon pointed out that the picture was taken with a twenty second exposure, which accounts for the long exhaust jet. Also, it’s worth pointing out that the exhaust exiting the missile is displaying classic isentropic flow characteristics. This means it’s operating at its design condition (Rockets are typically designed to provide maximum thrust at a certain environment). Considering this, I’d guess this was a short-range SAM. Beyond that, I will not speculate.

The flow looks either slightly underexpanded or isentropic at that altitude. From a design perspective, this strongly suggests short range SAM to me. From a military perspective, I wouldn't know; I was infantry, not air defense artillery.
