STAR WARS: Squadrons

So there has been some confusion and inconsistencies with the achievement so I figure I'd put what I did here for anybody that's struggling to get this like I was. For starters, lasers refers to the primary weapons and not the beam laser that you can equip to auxiliary.

I did this in a single player AI Fleet Battle. In case you don't know, when you select AI Fleet Battle and the menu pops up you can switch between Co-op and Single player at the top of the menu. I did this on Yavin because of the open space and I played as the New Republic because only hull damage counts towards the achievement and the empire doesn't have normal shielding and default more hull health which equals more damage. I played as an A-wing with the standard lasers so I could catch up to the AI ships easier and also because it's super easy to commit suicide when you need the morale meter to get that extra push against you and prolong the game. This achievement popped for me mid game and I had about 25 player kills and 30 ai kills. What makes this hard is in my experience the AI was pretty good at completing the objectives without me because of the Raider you get when the morale shifts. Time is the biggest factor. I did try to do Ranked Fleet battles but try as I might I couldn't get beyond the 45k mark no matter how much damage I did to players and AI however it may be better if you find the AI fleet battles just keep ending too quickly, bombers in Ranked tend to add the extra hull health to their which makes them a juicy 4000hp target. It's a combination of luck and skill, the luck being that the teams are even enough that the game lasts long and you can get the achievement with some good back and forth

I read on reddit that if you select Nadiri Dockyards, the AI for some reason just gets stuck on the map and you can just kill AI ships and the "players" that are stationary because of the bug. However when I tried it, like 5 times in a row all of the ships on my side and the enemy side just sat back and I couldn't even progress the game. Feel free to try it, I'm sure it'll work for some but I couldn't get it to work.

I've also seen where people said the rotary cannon on the bomber is the way to go too. That's mostly what I did in Ranked Fleet battles and is viable as well, just `not ultimately what I used. It does great damage output if your aim is good.

Finally there seems to be some debate on whether or not dealing damage to capital ships contributes. Based on the wording of the achievement I assume it does and the damage calculator is weird because I had one game with 100k damage to capital ships with only lasers and it didn't pop. The game I got it to pop I didn't do any damage to capital ships and strictly focused on "starfighter damage". Take that for what it's worth as I can't really confirm or deny that it counts towards it but I lean towards it doesn't. If someone can confirm otherwise please do so.

This is a strategy to prolong the length of Fleet battle vs AI matches, as that is the key to unlocking this achievement.
First of all, it is specifically primary laser damage against star fighters, there is a metric for this shown at the end of the match. I believe anyone that got this while attacking Capitol ships had some sort of glitch occur. I know the tracker definitely counts capital ships, but the achievement shouldn't unlock untill you have 50k+ star fighter damage.

I recommend using A wing, standard laser canon, and play on medium difficulty.
You'll want to be very diligent with switching power between shields and lasers using left and right on the D pad, shouldn't need to power up your engines at all.

The technique is to manipulate the "moral" meter to have the game constantly switch between offence and defence. When on offence, either team earns +5 moral per "player" kill (AI players with a name) and +1 moral per "AI" kill (will simply show "Tie fighter" when targeted.
On defense teams earn +10 per player kill and +3 for AI kills.
Because you earn more moral while on defense, you need to change the way you play depending on what you're currently on.
At the beginning of the match, use LT to select "All enemies", target the enemy raider, and press "Y" to have your squad attack it, then simple press "A" to cycle through enemies, and kill them as fast as possible with your laser canon. You'll either end up filling the moral meter and going on offense, or you'll get pushed back and go on the defensive.
While on offense, you want to use LT to select "enemy AI" and only kill the AI for +1 which should allow the other team to push you back after a few minutes. When on defense, LT and select "All enemies" and immediately target the enemy raider and have your squad attack it again, then focus on enemy players for +10 moral, which should push the enemy back in a few minutes. By repeating this back and forth, you should be able to drag the game out for a good 20 minutes or so. The achievement pops mid game, and you'll have dozens of kills before you unlock it. This takes a bit of hard work, but I've unlocked the achievement twice while using this technique, so with some tenacity, you can too!

Fleet Battles VS AI
Match Setting: Solo
Map: Yavin
Preferred Faction: New Republic
Difficulty: Easy

T-65 X-Wing
Primary Weapon: Czerka Guided Burst Canon
Left Auxiliary: Kyrotech Emergency Astromech Repair
Right Auxiliary: Krupx MG7-A Proton Torpedo
Countermeasures: ArMek H/M Seeker Warheads
Hull: Incom Ferroceramic Hull
Shields: Standard Incom Deflector
Engine: Incom Sublight Engine

Focus on the raiders. Use the torpedos then canons. Repeat. Go for the cruisers and the Star Destroyer once your squadron have stripped them of shields (when you hear that the shields are down).

I did this first time. I accidentally found this out by getting this without even trying on my brother's account so I could get his account to Level 5 so I could use it for boosting ranked match achievements. Copied the load out in my account, launched the game with the same settings, used the same tactics and pop!!!

Good luck.
