How did the use of landmines and fragmentation bombs make the war especially brutal for soldiers and civilians?

As we all know, landmines and fragmentation bombs are concealed underneath shrubbery and dirt surfaces where the target enemy is expected to pass. Though the soldiers where the ones who buried these explosives, they couldn’t trace everywhere they buried them. That means just like the civilians, they were at risk of falling prey to such explosives while moving through the dark and insecure shrapnel and passageways. And considering that anybody who stepped on such explosives ended up securing serious injuries if they didn’t die, that posed a great risk on their lives and made the mission more complicated.
