But yes, the larger scaled tracks are being upgraded with the new cascade units. We are at 63% complete. This was just the test model. Man portable actually. Only vaccuum prevented that needle from vaporizing. Acceleration protocols can be timed for geometric or straight scalar curves. You could have it light enough to not ruffle a feather, or you could max it out which would reduce any biological matter within the "bucket" to a thin, pink paste.
The bigger tracks can launch tons of material at a time. Of course, the more "magnetic" the material, the more efficient it'll operate. Iron chunks in the 800lbs range can be zipped out at relativistic velocities.
Just don't shoot 'em all off at once, or only on one side. Newton wouldn't like it very much.
