It's not just landmines that are trouble.
It's easy to mess up when your ration pack is similar to an unexploded cluster munition.
It's mainly the Soviet that are guilty of the disguised toy/bombs and yes they are mainly psywar weapons intended to terrorise. They are not the culprits.
It's the millions of mines like the Soviet and Chinese PMD that can be made for about $2 that cause the trouble.
