Vasilek automatic mortars, six rounds fired in succession, with 24 shells out in two seconds, then a few seconds to change a magazine, and another four shells were out.
Six mortars, continuously firing rapidly, calculated at 240 rounds a minute, were pulled by trucks. If they lacked shells, would they even be a mercenary-maintained army?
The sound of explosions didn't stop, surrounding Gao Yang were only a few people, several trucks full of shells were brought, and if these mortars were used up they would be discarded, and any leftover shells would also be discarded. For Gao Yang, everything else didn't count; the cost of taking these things away was higher than the value of the mortars and shells themselves, so why keep them?
If they're useless, of course they should all be fired. If it's said the area needs to be given a thorough shelling, then it must be shelled thoroughly.
