Once you've unlocked all of the weapons remember you need to get 10 kills with them
Edits: As mentioned in the comments section by Cenrail, you don't have to actually unlock each weapon, you can just pick it up from a someone else who dropped it and get the 10 kills needed.
Also matdan12 mentions, these requirements don't have to be met on the new maps. Any maps will do.
As Scruffy McGuffy, DBB Klikopedia and BigWorthless confirm, none of the challenges have to be done in specific classes apart from the obvious ones, snipe kills, LMG kills etc Therefore it's best to unlock the complete first tier of challenges first. Try to get 2 hours on Strike at Karkand done so the time starts counting for Sharqi and Oman as soon as possible too.
If you get the 10 kills with every weapon and it doesn't unlock. Simply get 10 more kills with the Famas in one match and it should unlock (Any DLC gun may work but the Famas definitely does)Not sure why this happens, but it seems to be common.
If that still doesn't work then you may need to get 10 kils with each weapon in one sitting, It seems that some counts are being reset when turning your 360 off
Thanks for all the extra tips in the comments, keep them coming and I'll keep adding them in.
The weapon sets needed are as follows, play 5 rounds of each
Heavy Gear weapon set includes FAMAS & QBB-95
EU Arms Race weapon set includes L85A2 & MG36
Snipers Delight weapon set includes QBU-88 & L96
Normal weapon set includes PP-19 & MK3A1 (you only need to get to level 8 on this rather than 17. You can quit after level 8 and getting two kills with each of the required weapons and it will still count however XP obtained will not)
This then leaves these two to unlock
G53 - 10 repairs and 1 repair torch kill (easily done)
QBZ-95B - this one takes a bit of time, you need to have G53 unlocked to unlock the assignment for this then get
50 rocket kills
Destroy 1 enemy vehicle with the repair torch
Win 5 rounds of conquest
For the conquest rounds set the required number of TKs to 10% in the map rotation settings and it will be very quick.
Remember for these last two guns only one player needs to unlock each. Once unlocked play some TDM and each player gets the 10 kills. As previously stated if the players who do not have the weapon unlocked kill the player who does and pick up their loadout the kills will count. Quickest method is team being killed keep respawning next to player doing the killing using a radio beacon (recon class)
To stop the parachuting in when using tge beacon place the beacon indoors and you will spawn on the ground. Factory on Sabalan Pipeline map is good for this
Also the server owner can move players to different teams to make it 3v1 with the player on their own getting the kilks. That speeds it up a bit as well giving them 3 to kill rather than 2. To do this hit start, server settings, manage players, select who you want to move, hit A and they will die and re-spawn on other team.
This method of using Gun Master still takes a bit of time (5-8 mins per round with 4 players) but it means you don't need the 6 hours play time to unlock the PP-19 and MK3A1 and don't need support class to level up 4 times for the QBB-95
You don't have these weapons at the start of the DLC. These are all weapons you must unlock by completing assignments! Here is a link of said assignments: Assignments
You must complete the Tier 1 assignments to unlock the 2nd tier assignments for each class.
Assault Tier 1: FAMAS – “Best Friend Forever”
- 10 Revives
- 10 Heals
Play as the Assault class with med-packs equipped. Revive 10 teammates and get 10 heals and you receive the FAMAS which is an excellent assault rifle.
Assault Tier 2: L85A2 – “Professional Russian”
- 100 Assault rifle kills
- 20 Grenade launcher kills
- Win 5 Squad Deathmatch rounds
Bust out that newly acquired Famas and kill 100 with it, use the M320 grenade launcher attachment (unlocked at 11000xp in Assault) and get 20 kills with that. Then play some Squad Deathmatch and get 5 wins.
Engineer Tier 1: G53 – “Fixing it”
- 10 Repairs
- 1 Kill with the repair tool
Play as Engineer class and keep that repair tool handy! Get 10 repairs on team vehicles and get 1 kill.. preferably sneak up behind someone and burn them to death!
Engineer Tier 2: QBZ-95B – “It goes Boom!”
- 50 Kills with AT rocket
- 1 Enemy vehicle destroyed using the repair tool
- Win 5 Conquest rounds
Play as Engineer, use the SMAW (US) or the RPG (RU) and kill folks. Blowing up a tank with 2 people in it with a Rocket will count toward your total. Destroying a vehicle with the repair tool can be kinda tricky, but you can destroy anything! What I mean is, an enemy spawn beacon, a MAV or a T-UGS will all count. I personally got mine by destroying an LAV at an enemy spawn point with no one in it. Then be on the winning team for 5 rounds of Conquest.
Support Tier 1: QBB-95 – “Let it rain”
- 20 Kills with Light Machine Guns
- 2 Mortar kills
Get 20 kills with any LMG in any match. Now for the mortal kills, I personally did not have the mortal unlocked. But I came across a poor fellow in a not so safe area with his mortar deployed; I killed him and took his kit and got my mortar kills that way.
Support Tier 2: MG36 – “Keep your head down”
- 100 Kills with Light MG
- 50 Suppression Assists
- 50 Ammo Resupply Assists
Get lots of kills with that new QBB that you just got while getting some suppression assists here and there. Keep throwing down ammo boxes for teammates and snipers hanging back and you'll have that done in no time.
Recon Tier 1: QBU-88 – “Specops”
- 20 Kills with sniper
- 6 Laser designations
You have to use a sniper rifle for this assignment.. can't use a PDW weapon this time. Get 20 kills any way you can. Now for the laser designations you must use the SOFLAM (unlocked at 26000 recon score) and lock on to vehicles in the area. Once you lock onto a vehicle and have solid tone.. that counts as a designation.
Recon Tier 2: L96 – “Creeping Death”
- 50 Headshots
- 50 Spot Assists
- 5 Knife kills
The beauty of this assignment is that it can be done with any class. So any headshot and any spot assist (by pressing Select while targeting an enemy or vehicle) will count. Same goes for knife kills!
Any class Tier 1: PP-19 – “Familiar Territory”
- ARM 10 MCOM stations
- 10 Flag captures
- 2 Hours played on Strike at Karkand
Play some Rush and you just have to arm the M-Com, it doesn't have to explode! So if you arm one, an enemy defuses it and you arm it again.. that counts as two. Play some conquest and cap those flags! Play specifically on the map "Strike at Karkand" for two hours.
Any class Tier 2: MK3A1 – “Scarred Veteran”
- 10 Kills with the PP-19
- 6 Kills with the DPV Jeep
- 10 Kills with the BTR-90 APC
- 2 Hours played on Sharqi Peninsula
- 2 Hours played on Gulf of Oman
Once you unlock the PP-19 (which is a pretty good gun) get 10 kills with it. Make sure you are in the DPV (not the VDV Buggy) and run down some enemies in it. I personally just ran loops on the streets of Gulf of Oman and ran people down. The BTR-90 is generally only found on the Russian team of Gulf of Oman on Conquest only (not Conquest Assault). Then play 2 hours each on the specific maps.
