Add event mouseDown and mouseMove to my own class

Question

I have a problem.

I need to add a MouseDown event to my own class (Unidad.cs) but I don't know how to do it. I have a class that extends from pictureBox and I need a MouseDown and MouseMove event to move the pictureBox, how can I do it? And... It goes always to the exact pictureBox? I mean, I will have 20 (for example) "Unidad" objects and I want to move only the Unidad object that is clicked with the mouse.

My class:

public class Unidad : PictureBox
{
    //Constructor
    public Unidad(string nombre, string tipo, int movimiento, int ha, int hp, int fuerza, int resistencia, int heridas, int iniciativa, int ataques, int liderazgo, int coste, string rutaImagen)
    {
        tipoUnidad = tipo;
        movimientoUnidad = movimiento;
        nombreUnidad = nombre;
        costeUnidad = coste;
        haUnidad = ha;
        hpUnidad = hp;
        fuerzaUnidad = fuerza;
        resistenciaUnidad = resistencia;
        iniciativaUnidad = iniciativa;
        ataquesUnidad = ataques;
        liderazgoUnidad = liderazgo;

        object O = Resources.ResourceManager.GetObject(rutaImagen); 
        dibujoUnidad = new PictureBox();
        dibujoUnidad.SizeMode = PictureBoxSizeMode.StretchImage;
        dibujoUnidad.ClientSize = new Size(145, 67);
        dibujoUnidad.Image = (Image)O;
    }

    //Propiedades
    public string nombreUnidad { get; set; }
    public string tipoUnidad { get; set; }
    public int movimientoUnidad { get; set; }
    public int costeUnidad { get; set; }
    public int haUnidad { get; set; }
    public int hpUnidad { get; set; }
    public int fuerzaUnidad { get; set; }
    public int resistenciaUnidad { get; set; }
    public int heridasUnidad { get; set; }
    public int iniciativaUnidad { get; set; }
    public int ataquesUnidad { get; set; }
    public int liderazgoUnidad { get; set; }
    public PictureBox dibujoUnidad { get; set; }

    //Método para dibujar unidad
    public void Colocar(Point p, Control control, Image imagen)
    {
        using (Graphics g = control.CreateGraphics())
        {
            using (Pen pen = new Pen(Color.Red, 2))
            {
                g.DrawImage(imagen, p);
            }
        }
    }
}

Thanks!

EDIT 1:

I can do it with that at the end of my "Unidad.cs":

public void Colocar(Control control, Unidad unidad, Point p)//(Point p, Control control, Image imagen)
    {
                control.Controls.Add(unidad);
    }

    protected override void OnMouseDown(MouseEventArgs e)
    {
        //Do Stuff here
        base.OnMouseDown(e);
        MessageBox.Show("HOLA");
    }

The problem that I have now is that I don't have the image, I saw a black rectangle, or grey rectangle if I don't use the BackColor command, that when I click on it, it shows me a MessageBox, but I can't put the correct image or the correct location. Anyone can help me?

You are inheriting from Picturebox so you can override the Mouse events

 public class Unidad : PictureBox
    {
        protected override void OnMouseDown(MouseEventArgs e)
        {
            //Do Stuff here
            base.OnMouseDown(e);
        }
    }

I added a Panel to my form, "Form1" called "picContainer"

public Form1()
{
      InitializeComponent();  

      picContainer.Controls.Add(new MyPictureClass()
      {
            Image = imageList1.Images[0],
      }
     );
}

I set the image from the image container.
