There was a faint whirring sound as the handle on the detonator was pulled out to its fullest extent, and then a whine as it was pushed home.Bricks and concrete smashed into the far side of the APC, as a portion of the charge blew back, but most of it belched forward, bursting apart the last ten feet of the pipe as if it were a paper straw and scattering rocket warheads down the length of the street.Masses of secondary explosions marked their impacts and the road was lit like day. As the echo of the last died away, Revell looked out round the side of the APC. He didn’t need the intensifier. Flames were coming from the front- mounted engine of the self-propelled gun and illuminating the scene. Every fitting had been blasted from the vehicle and both its tracks were broken. Smoke boiled from holes in the armour, but there was no sign of the crew.And there was no sign of the Russian engineers or infantry either, at first. Of the hundred and fifty men who had been there, not one remained on the road.
