Gia Lai, Cochin
One of the nice things about Cochin, as a place to test explosives, was that there was so much unexploded ordnance laying around, which ordnance the Cochinese Army made some effort to clear, that surface explosions, even fairly large ones, were so common as to not incite commentary. Or even to be noticed.
Sig wondered, Do you suppose that was in Carrera's mind when he selected this place for testing? Hmmm . . . might have been.
Sig swatted away a mosquito as he and a Cochinese sapper, Sergeant Tranh, a combat engineer whose commander was being paid twenty FSD a week for the use of him, primed a plastic barrel with blasting cap and fuse. Siegal watched the sapper carefully tap the cap, held in his right hand, one wrist slapping against the other to knock out any dirt which might be in the cap and which could interfere with detonation. Tranh then inserted the fuse, about six feet in length, into the cap. He then turned the cap, fuse inserted, until the cap's opening was pointed away from him. Lastly, he crimped the cap to hold the fuse in place.
In French, Siegal said "Ok, Tranh. Set the igniter and prepare to pull." The little Cochinese inserted the other length of fuse into a pull igniter and turned a knob to screw the fuse in tight. He looked up at Siegal for the word to go. Siegal looked at his watch and nodded. The Vietnamese shouted a warning, three times, and pulled the small metal ring at the end of the igniter opposite the fuse. Smoke began to curl upward. Then the two retired to a bunker nearby where Han already waited. Siegal consulted his watch once they were safe inside.
It had not proven possible yet for Sig to obtain anywhere near enough caltrops for even a single test. Oh, he could have had ten thousand made by hand. But they'd have been non-standard, of variable strength, size, and weight, and thus useless for testing purposes. Arrangements for some limited manufacture of enough caltrops to run several more tests were still being made. Sig was also working with a local sewage treatment plant to process shit into a kind of plastic for mass manufacture of the scatterable obstacles. A few bribes to the commander of a local combat engineer battalion who had given Sig the use of Sapper Tranh had provided several tons of both high and low explosive.
The test 'caltrop projector,' therefore, had only a loose packing of gravel in place of the caltrops. For this test Siegal only wished to find out whether or not a linear shaped charge could be used to cut the top off of the barrel just prior to the main bursting charge, a plasticized ammonium nitrate mix, sending the payload up and out. Siegal didn't have the physics to predetermine how much explosive was required to spread eight or ten thousand very light and un-aerodynamic caltrops around an area several hundred meters in radius. He intended to experiment until he found out. He mused, from time to time, on the question of whether a clever sergeant—or rather a bunch of clever sergeants—weren't more cost effective than a high brow scientist . . . or even a number of them.
As the second hand on Siegel's watch swung round, he hunched himself lower into the bunker, Tranh following suit. The sapper reached out one hand to push Han's head lower.
It's hardly the first time a man ever pushed my head down, the girl thought. This one, at least, means me well by it.
Then a half-pound of RDX based linear shaped charge and twenty-eight pounds of ammonium nitrate-based explosive rocked the earth. A pattering of silver painted gravel flew up and then fell on and around Siegel's bunker.
