blind
adj.— «Top Government sources have told The Sunday Express that a majority of the 2,000-strong Krasnopol inventory has been found defective: the shell, priced over Rs 15 lakh per piece, hits the target accurately during test-firing but fails to explode on impact. In military parlance, these shells are “blind” or duds.» —“Most of Krasnopol ammo for Bofors guns turn out duds” by Shishir Gupta in New Delhi Sunday Express (India) Nov. 26, 2006.
