The bulk update request #13043 has been approved by @nonamethanks.
create implication dynamite -> explosive
create implication tnt -> explosive
create implication bomb -> explosive
create implication pipe_bomb -> bomb
create implication time_bomb -> bomb
So, some of these explosive-related tags were not implicated to the main "explosive" tags for some reason. I think this should be added for consistency.
Also, I think there should be a clarification about the difference between grenade and bomb, since many of the post featuring grenade were tagged with "bomb" instead. Based on my knowledge, a grenade should be a weaponized explosives with fixed automated fuses, but a bomb is manually lit by the user.
