IMO, there is no better feeling than understanding your squad-mates in SQDM and owning everything! On Armored Kill SQDM, we all understood each other. I had frag for my sqaud specalozation, another had ammo, another had flak, and the other had sprint. We would switch it up sometimes. There was never a time when two players had the same squad specialization. Another epic moment was when we took the BMP and all of us had this general understanding. We moved with the tank. There were two medics, a support and engi. All of this was done without a mic.
Now, at first, I thought "OMG this squad sucks! They're dead last!". Some experimenting and cooperation later we were catching up to the leading squad. We lost by 5 kills

It was a valiant effort nonetheless.
The same thing happened on Seine SQDM.... my teammates unfortunately left the lobby... I was fooling around with the recon class, until a GREAT player spawned into my squad. He was a medic, and he was owning everyone. I said "🤬 it!" and picked up a medic kit from a dead russian medic. Fortunately, he was rocking the M16A3 with ACOG, and undersling barrel so I got used to that gun pretty fast. I died and respawned with my own M16A3. Iron sights, foregrip and something else (no suppressors). Two Supports joined our squad and all of us stared working as a squad. Each contributed with their own squad specalizations. We finally got the tank, and all of us stuck with it, protecting it and attracting a lot of wanted attention.
All of this took place on this 4 floor building. There are two entrances and about 3 angles of covering fire .
This one:
At some point, we lost it, and we kept on flanking from the alleyway on the right.
