Gattor here is what we have to do :
The Whites of Their Eyes: Kill an enemy from within 15 meters.
In the first task, you need to get up close. In close-quarters fights, shotguns, assault rifles, and SMGs are good choices for winning duels and getting quick kills. Don’t underestimate your sidearm though; if you’ve softened up the enemy with higher calibers, pistols and revolvers are perfect for following through when you don’t have time for a reload. The streets of Rotterdam and its demolished map sibling Devastationcould be a good fit for this task.
Relentless Advance: Get ten offensive kills.
An offensive kill is when you defeat an enemy while trying to capture a control point held by the other team. To get ten of these more easily, bring your squad, keep an eye on the capture area of the objective you’re attacking, and follow up every kill by advancing towards your target.
Improved Visibility: Spot ten enemies with Spotting Flares in one life.
Spotting is a great way for Recon players to give extra eyes to their teammates. Enemies are often spotted one by one with the Spotting Scope, but for this task, we want you to use a (potentially) more efficient method. Equip your Recon with the Flare Gun gadget and shoot out flares over contested objectives or groups of enemies. This can reveal many foes on a wide area.
Hold the Line: Get ten defensive kills.
Don’t give them an inch. Be mindful that the ground you're standing on is worth dying for. To get ten defensive kills, be in the capture area for the objective you’re defending. Take advantage of Resupply Stations and defensive Fortifications to make sure the bullets are distributed according to plan.
Knock Down: Destroy ten Fortifications.
Bring it down, smoke ‘em out. Using explosives to destroy Fortifications like barbed wire, sandbags, and barricades may reveal an exposed flank, or give you and your teammates a clear sightline to anyone behind them. Do it ten times, and you’ll gain Chapter XP and a way forward in the challenge tree.
Shore Up: Build five Fortifications.
Want to be constructive instead? Keep those sandbags and that barbed wire coming. Invaluable for defense, Fortifications impede the enemy and keep you safe from snipers. Any class can build these, but the Support class is the Fortification master. Hit the toolbox button near flags and you’ll see silhouettes of what can be built.
Keep Them Running: Repair teammates’ vehicles for 150 health.
Support class players have a nifty ace up their sleeve, the blowtorch repair tool. Bring this out when a friendly ride needs a do-over (it’s the same button used for building Fortifications). Remember that if a tank, halftrack, or other vehicle is damaged, there’s a reason for it; be wary of enemy presence before going for the repair. Another pro tip: use the vehicle itself as cover.
Operational Success: Win three matches.
Keep track of your objectives and work with your teammates to achieve victory – threefold. This can be done in any game mode, so pick your favorite, or, if you’re in a hurry, a quick one like Team Deathmatch. Another great way to tackle this is by playing a Grand Operation, perhaps the latest called Battle of Hannut. Epic scale and mode variety is guaranteed!
On Two Feet: Heal or revive teammates ten times.
If you’re playing as the Medic class, you can always use your Syringe to revive fallen team mates. If you’ve equipped the Bandages or Medical Crate gadget, you can use these on the battlefield to keep your teammates healthy. Fancy playing as another class? Use Buddy Revives on players bleeding out – note that they must be part of your squad, though.
Fire in the Hole: Arm an objective in Airborne, Rush, or Frontlines.
Securing the target is only half the job, you still need to light the fuse. Objectives in Airborne, Frontlines, and Rush need someone to take the risk of arming them. That someone could be you. Be aware that the person carrying the explosives is highly sought-after by the enemy, so bring some assistance when trying to pull off this stunt.
Common Goal: Complete three Squad Orders.
In the list of squad members in the lower left corner of the screen, you’ll see a star-shaped symbol on one of the names. This is the squad leader. If this is you, be sure to give orders. Simply look at an objective and hit the danger ping button and your squad will see where to focus their efforts. If you’re a squad member, follow these orders – it will mean extra points. This task requires three completed Squad Orders and can be completed by both squad leaders and members.
Device Disabled: Disarm an armed objective.
Modes like Airborne and Rush have an explosive touch, as they revolve around the arming of certain objects with explosives. If you’re on the defending side, don’t give up because the enemy managed to arm an objective. Push them back and go for the disarm by interacting with the object. Make sure to have your back covered as this area is of crucial interest to both teams.
Pineapple Mash: Deal 500 damage using hand grenades.
Grenades come in many forms. Some detonate after a short time, some on impact, and some burst into a sea of flames. There are grenades ideal for vehicles, and grenades feared by infantry. So, head to the Company menu and choose your favorite throwable. Toss grenades on highly-populated areas like flags or close-quarter areas where enemies have nowhere to run.
