Medals - Weapons and Items
Here, we explain how to earn medals, Since many of these items overlap with achievement cancellation, I think this is useful for achievement cancellation purposes.
Weapons and Items
Outstanding Sniper (Achievement Unlocked)
Defeat 350 enemies with a rifle
If you earn each Rifle Follower medal, you can automatically complete it. If you use a rifle in normal play, you probably manage to achieve it before you know it.
Target (Achievement Unlocked)
Defeat 350 enemies while using Iron Sight with any weapon
I don't think you can earn numbers unless you consciously do it. Set the difficulty to the easiest "Civilian" and set the sub-weapon (machine gun) to no scope. Once you start a mission, set your weapon to Iron Sight mode and keep charging at enemies to achieve the goal.
Also, for the medal "Aiming Structure," rifles require killing enemies with iron sights, so if you start with "Aiming Structure," you can also rack up the "Aim at the Target" count in parallel.
If finding enemies is a hassle, as a clever technique, gather about 10~20 unconscious soldiers to save, then repeatedly load them after defeating them to rack up your count. By the way, saving and loading can cause unconscious soldiers to disappear, so it's good to collect more.
Don't Touch Danger (Achievement Unlock Target)
Craft corpses, objects, and vehicles to bury 20 soldiers
I don't think you can earn numbers unless you consciously do it.
If racking up counts is too much trouble, gather the unconscious soldiers and save them. After defeating one enemy, you can hide grenades and shoot them with guns to explode to rapidly increase your count. After that, just load and repeat to complete the task quickly.
Target Structure (Achievement Unlock Target)
Defeat 150 enemies while using Ironsight with a rifle
I don't think you can earn numbers unless you consciously do it. Set the difficulty to the easiest "Civilian" and set the rifle to no scope. Once you start a mission, set your rifle to iron sight mode and charge at enemies to keep firing nonstop. Distance doesn't matter, so if you hit from close, you'll usually get hit. It's easier to choose a rifle with high rate of fire.

Bloodshed Enough to Fall (Achievement Unlocked)
Defeat 50 enemies with traps
I don't think you can earn numbers unless you consciously do it.
If racking up counts is too much trouble, gather the unconscious soldiers and place landmines to save the game. If you shoot a landmine and detonate it, you can rapidly increase the count. After that, just load and repeat to complete the task quickly.
Gunslinger (Achievement Unlocked)
Defeat 150 enemies with a handgun
If you earn the medals for 'Handguns Are Too Loud,' you can automatically complete this milestone. Even in normal play, if you use a handgun for ghost kills, you should be able to achieve it before you know it.
Reliable Guns (Achievement Unlock)
Defeat 50 soldiers with heavy weapons
It is necessary to defeat soldiers with so-called anti-tank and vehicle-oriented weapons, such as "portable anti-tank weapons," "PIAT," and ".55 anti-tank rifles." Some maps have quite a few options, but since the ammo count is low, you need to repeat several times.
If racking up counts is too much trouble, gather the unconscious soldiers and save them. With "Portable Anti-Tank Weapons" or "PIAT," you can take out all enemies with just one shot, so you can quickly increase your count. After that, just load and repeat to complete the task quickly.
Scaramouche (Achievement Unlocked)
Defeat 300 enemies with a sub-weapon
If you earn each medal for 'Outstanding Sub-Weapon Master,' you can automatically complete it. Even in regular play, if you use a submachine gun in a chaotic battle, you might be able to achieve it before you know it.
What I Picked Up Is Mine (Achievement Unlocked)
Defeat 50 enemy soldiers with the weapons you find
Set the difficulty to the easiest "Civilian" and use weapons dropped by enemies to defeat them one after another. Enemies will always drop their guns, so you won't have trouble running out of guns or ammo.
Master multiple skills (achievement unlock target)
Defeat enemies each with 20 types of weapons
You can complete this using only weapons obtained from workbenches or kill challenges. You can also rack up counts with weapons that only drop inside the stage.
Weapon Master (Achievement Unlock)
Reach 'Master' with all weapon types
You can achieve this by obtaining medals for "Handgun Enthusiasts," "Excellent Sub-Weapon User," and "Rifle Enthusiast."
Handguns are noisy.
Handguns are noisy (achievement unlock target)
Earn 6 Handgun Mastery Medals (Gold)
Collect 6 gold medals from the following 'Master of ○○'. You can achieve it even without DLC weapons.
Master of ○○
Perform 50 Ghost Kills when ○○ is used
Ghost kills can be achieved when you defeat an opponent with a handgun, without being noticed by other enemies due to gunfire or visual sight. So basically, the main goal is to defeat enemies when there are no other enemies nearby. If you're not good at aiming, you can still knock the opponent out in melee before killing, so this method is probably easier. The handgun is designed to keep the firing sound as low as possible, and when enemies are nearby, switch to 'subsonic rounds' for use.
Some weapons lack suppressors and similar equipment, so the firing noise is quite loud. In that case, you might need to knock out enemies and carry them to a place where no one else is around, which can be quite troublesome. Or maybe it's better to knock out all the enemies around you.
Since it's quite a tedious task, it might be faster to repeatedly collect stunned soldiers, save, increase kill counts, and reload.
Outstanding Sub-Weapon User
Outstanding Sub-Weapon User (Achievement Unlocked)
Earn 8 Mastery Medals (Gold) for the sub-weapon
Collect 8 gold medals from the following 'Master of ○○'. You can achieve it even without DLC weapons.
Master of ○○
Record 150 kills with ○○
All you have to do is defeat the enemies, so set the difficulty to 'Civilian' and charge at them with lots of shots.
Since it's quite a tedious task, it might be faster to repeatedly collect stunned soldiers, save, increase kill counts, and reload.
rifle enthusiast
Rifle Enthusiast (Achievement Unlock Target)
Earn 7 Gold Mastery Medals for Rifles
Collect 7 gold medals from the following 'Master of ○○'. You can achieve it even without DLC weapons.
Master of ○○
Record 50 headshots from a distance of over 100m when using ○○
There aren't many places where you can shoot a lot from more than 100 meters away, so it's better to choose places like Mission 1 or Mission 6 where you can shoot many targets right after the mission starts.
Since it's quite a tedious task, it might be faster to repeatedly collect stunned soldiers, save, increase kill counts, and reload. However, you must shoot at least 100 meters away from the unconscious soldier.
