Mini-SAM, especially with the Command Centre and the Giraffe radar. Man-portable it ain’t, rather Jeep-portable. And I think that’s basically it, a low-maintenance lightweight SAM that can be mounted anywhere a .50cal machine gun would fit.
No way the system can intercept incoming missiles. I say man-in-the-loop systems can’t do that at all, except under very special and very lucky circumstances.
But it can keep small tactical UAVs and non-ATGM’d helicopters away.
