40-barreled 122-mm BM21 rocket launchers, at maximum firing rate, can fire all forty rockets in twenty seconds.
Twenty-four 40-barreled rocket launchers, firing in a salvo within twenty seconds, pour out 960 rockets, concentrating and covering the not-so-wide frontline positions, and judging by the height of the rocket explosions, they all used airburst fuzes, thus bringing a rain of steel to the positions.
The advantage of rockets is their rapid firing rate and powerful firepower, but their disadvantage is poor accuracy and low power, making them less effective against hardened targets. However, when it comes to hitting infantry, nothing is more terrifying than a salvo of rocket barrage.
This is a typical, highly targeted anti-infantry fire preparation. If Gao Yang and the others were still on the position during this round of rocket attacks, they wouldn't survive.
