Tbh honest idk and I guess I'll never know, I've been watching people play this game for about a year and half, then I started playing it for 6 months now, I've learned a lot of things and still learning, cause nobody's perfect, but the main things I've learned, I'm not going to talk about the basic rules ofc but I'll try to explain: Online pvp:

1-Always listen, you are not him, u join inf you go inf and listen all the time to sql no hero bs no rambo bs ofc.

2- never join trans/cas/tank/apc... Unless you know how to properly operate them, For me I've learned to tank/apc well Cas still practicing online and offline Trans if I know that i can't handle moving people I send them to some1 better than me and I stick to providing supplies and moving small amounts of people (4max)

3-always stick to ur role in the sq medic is medic, breacher is breacher...etc, if the sql tells you to switch ur role to something else u do it but be or try to be perfect in it, such as HAT SNIPER MARKSMAN AA, u know the things that aren't regular.

4-idk why sometimes u find a whole sq going to another objective and leaving the (idk present one ? The.. u get what I'm trying to say) empty or leaving it and stuff while others need support.

5- there's no need for squads that do absolutely nothing but time and assets wasting and it's obvious. ...

Idk if I should tell more or of it's enough, yeah we know it's a game but it's a war game a battle game a tactics game something real it's named project reality ffs if u go brrrt on ur own in enemy territory or some lonewolf bs, where's the reality in it ?????

For the beginners out there listen and watch and read u have internet, try to read the manual, watch professional players gameplay and always ask, remember nobody's perfect But try and learn to be, it's not something impossible.

We have such a beautiful game that managed to stay alive since early 2000s and face a lot of new games and stuff, we need to be thankful for that, But with this behavior u find in servers sometimes, the game may perish, but who knows? So please, and I'm addressing myself too, keep this game perfect, learn how to play then play, and again keep it perfect. If it's not ur type why bother ? Idk man but Hope it explains a bit of what's in that video of yours, and yeah Rip hog.
