Hi. I found this photo on internet, and these shells look somewhat "weird" to me. The picture apparently was taken not so long ago in Irak by an EOD team. I haven't any measurement nor any idea of the period they were fired or for which purpose (combat, training, proof?) . It looks like there's no fuze and the intriguing detail is the 2 groves on the noze of the projectiles. Can someone shed some light on this? Thanks.
