How to unlock the We don't need a stretcher. We need a mop! achievement in Zombie Army Trilogy - Definitive Guide
By the end of my first playthrough I had around 30 kills while playing with a partner. By the time you collect all the bottles and gold bars and have played all horde maps to wave 10 and completed the game on Sniper Elite difficulty you should definitely have this achievement.
Suicide Zombies are the ones that glow orange and run at you with their arm swinging holding a grenade. You will encounter Suicide Zombies a lot during the campaign missions as well as in the later rounds of Horde Mode. It is most likely that the trophy will come naturally but if not then just replay the campaign on Cadet difficulty and set the Enemy Spawn to 'For 4 players', which will drastically increase the number of enemies in the each level.
Suicide Zombies scream loud when approaching. Once they arrive, they will try to explode on-top of you. Kicking them will make them explode so you must try to shoot them before they reach you. This will also make the grenade kill any surrounding zombies. You should easily get this achievement before finish the first campaign run. If you want to farm them, in the last section of Episode 1, Chapter 4: 'Library of Evil', many of these guys jumping out the ground like land mines; just shoot them and the kills will count.
