Make vehicles attack nearest Nutral marker

[FG28_Kodiak]

if you use the Missionmarkerclass from narvy

internal class MissionMarker
    {
        internal double x;
        internal double y;
        internal int army;
        internal MissionMarker(double x, double y, int army) { this.x = x; this.y = y; this.army = army; }
    }

then you should use 0 for neutral, 1 for red and 2 for blue. In mis-file a neutral frontmarker has also the value 0
