The [crM] is from Bex notation, which is another extension of Betza notation than the XBetza that is used by the Interactive Diagram. "Capture without moving" a.k.a. rifle capture is written in XBetza as a 2-leg move back and forth, where the first leg captures in the normal chess way, and the second then returns the piece to where it came from. So cabK describes a King move that captures (c), and the again (a) a King move that steps back (b). So it would rifle-capture to all adjacent squares.For a sliding rifle capture such as a Rook you would have to write caibR, where the i in the second leg ('iso') indicates it has to be as many steps as the previous leg.
Distant rifle capture is excessively dangerous, especially when it jumps. There basically is no defense against it other than moving the threatened piece away. Which you can do for only one of the pieces that gets forked. And the alternative move for the War Machine has an enormous forking power. So my guess is that it would be way too strong, and that the whole game will just degenerate into War Machines massacring the opponent.
Also note that the alternative move for the Archer makes it a very slow piece. Although it is technically possible to use it in the opponent's camp, you will have to invest so many tempi to get it there, that you probably cannot afford it. To a somewhat lesser extent this also applies to pieces that can only step 2 squares. But if such pieces stay in their own camp, the defender has a large majority there, that you will not be able to beat with only your fast-moving pieces, not even when you are several of those ahead. You can only overcome the defence by bringing over your slow pieces, which will make the game very long.
