for me,

1. Try not to expose yourself from being seen on minimap or spot by someone else with Q, MAV, Sensors, don't simply fire ur gun if not necessary, going by less expose path, or use sliencers, don't make too much noise like running too much in enemy territory , if u want do some stealth surprise kill

2. do not stay at the same spot too long, camping in bf4 = suicidal unless you are at the spot other ppl hard to reach you

3. Do not searching enemies only by your eyes, always listen, there's always footsteps and guns noise if enemies around, so you can pin point them, always look at minimap scan enemies, so you know where enemies possibly are, help spotting enemies so your teammates will aware of them and take them down.
(in real life battlefield, enemies are much harder to see than in battlefield game)

4. Don't go alone by urself, always go with squad members, if you are the last man in squad, do not engage enemies, stay alive, stay stealth, until your squad members respawn at you.

Now I can only think all this battlefield 4 basics , anyone feel free to add
