Three types of 300 mm rockets are available, the BRE2 (190 kg HE warhead, lethal radius of 100 metres and range of 60 to 130 km), the BRC3 cargo rocket (623 submunitions capable to penetrate up to 50 mm steel armour, with a range of 20 to 70 km), and the BRC4 (480 submunitions and 60 to 130 km range).
Although there are some areas where there is less risk with unitary munitions--it is unlikely that children will mistake the average 454 kg bomb for a toy--subsequent post-mission detonation would lead to far greater damage and a wider lethal radius than a submunition with grams, not kilos, of explosive.
In fact, the diagram given herewith (results of arena test) provides the answer: on a conventional mortar fragmentation bomb (thus exploding before impact), the lethal radius under its nose is virtually null when it dives in a semi-vertical position, particularly over a trench.
