This is one reason why cluster bombs are banned (albeit that's ignored) and why anti-personnel mines should be banned (there's the Ottawa treaty but the bigger forces like the US, Russia, China, India and Pakistan have not signed it). As an alternative the US's ATACMS rockets have a variant with tungsten shrapnel, which has been used against Russian force gatherings and transport columns like a giant shotgun blast but without the leftover unexploded ordnance.
