I think it'd be awesome if the Shilka could be interoperable with the one in SteelBeasts.

If SB could export the ground clutter & object electronic signatures as well as the optical signatures and movement/location cues into the Radar and "Computer" system of SAMSIM, while Sam Sim exports the firing solution and trajectories of the rounds into SB.

But that would mean a lot of work and an agreement between Hpasp and eSim.
