Battlefield 1

If you are a Battlefield 1 veteran and have played the previous DLC add-ons, then you should be familiar with this type of achievement. In this specific case, each class has two new weapons along with one new revolver and one new melee weapon that must be unlocked by completing weapon assignments (listed below). Once each weapon is unlocked, you must then perform at least one kill with it. The achievement tracker should increase by 10% as you perform your first kill with each new weapon.

It's also worth noting that if you pick up a new weapon from an enemy and perform a kill with it, this will count towards the achievement even if you have not personally unlocked the weapon yet. This can help if you are stuck on a weapon assignment or if you don’t mind boosting.

Assault

RSC SMG Factory

Perform 50 kills as an Assult
Self-explanatory.

RSC SMG Optical

Perform 50 kills with the RSC SMG Factory
This is one of the two new weapons added to the Assault class and is listed above. This is a short ranged weapon with a very small clip but packs a big punch. This is best used in trenches or other close quarters environments.

In a round, perform 300 Vehicle Damage using explosives
This is best done with the AT Rocket, Anti-Tank Mines, Anti-Tank Grenades and/or Dynamite. If you are having trouble earning this in standard game modes, try Operations. A round of Operations can be quite long and only ends once one of the teams wins or the map changes.

Medic

Howell Automatic Factory

Perform 50 kills as a Medic
Self-explanatory.

Howell Automatic Sniper

Perform 50 kills with the Howell Automatic Factory
This is one of two new weapons added to the Medic class and is listed above. This weapon is a semi-automatic rifle that has decent range and good damage. The only issue is that the sights are offset to the side and will take a little getting used to.

In around, perform 600 points of healing
Focus on sticking next to teammates and constantly dropping med kits. If you are having trouble earning this in standard game modes, try Operations. A round of Operations can be quite long and only ends once one of the teams wins or the map changes.

Support

IMG 08/18 Low Weight

Perform 50 kills as a Support
Self-explanatory.

IMG 08/18 Suppressive

Perform 50 kills with the IMG 08/18 Low Weight
This is one of the two new weapons added to the Support class and is listed above. This weapon is very similar to many of the Support weapons where it is decent while standing put becomes very useful when laying prone. The recoil nearly goes away and allows you to laydown very effective suppressive fire even at long ranges.

In a round, perform 100 resupplies
Focus on sticking next to teammates and constantly dropping ammo kits. If you are having trouble earning this in standard game modes, try Operations. A round of Operations can be quite long and only ends once one of the teams wins or the map changes.

Scout

Ross MkIII Marksman

Perform 50 kills as a Scout
Self-explanatory.

M1917 Enfield Infantry

Perform 50 kills with the Ross MkIII Marksman
This is one of the two new weapons added to the Scout class and is listed above. It is a powerful bolt-action sniper rifle that is very similar to the Gewehr models. This is a weapon that is best used at a long distance.

Accumulate 2,500 meters of headshots using Single-Action rifles
Luckily, this is cumulative and does not need to be done in a single match since that would make this task nearly impossible. Equip any bolt-action sniper rifle of your choice and look to earn headshot kills. The longer the headshot the better as they will add more distance to the 2,500 total that you need.

Sidearm (Can be used by any class)

Revolver MkVI

Kill 25 different enemies using Revolvers
This task is as strict as its description. You must kill 25 different Gamertags with Revolvers. Killing the same enemy more than once will only count as one kill towards this requirement. Equip all of your classes with any sidearm that has ‘Revolver’ in its name and focus on using your sidearm to kill enemies. Obviously, unaware enemies are the easiest to kill and so focus on flanking the enemy.

Melee (Can be used by any class)

Broken Bottle

Get 5 kills with the Wine Bottle
The unbroken Wine Bottle is a melee weapon that cannot be equipped in the menus and must be picked up in the environment on the three new ground based maps. Please refer to the “Modern Technology” achievement description above for full details on how to earn these kills.
