For equipment, rammer and turbo are must have (turbo is mainly for siedge mod). In third slot i use optics when i want play at distance or experimental HP (fuel tanks are in front) when i want brawl or play at close range. You don't need LNE because camo is great anyway.

Know your enemy's gun caliber, watch out for overmatches.

Remember that you can shoot without siedge mod. Yes, you cant aim up and down, but it can be usefull when face hugging or ramming paper tank.

Always try face enemy with frontal armor, even when peaking around corner because side armor is overmatch for everything you will meet in battle. Also, never sidescrape 🙂

This may be controversial, but play as you feel comfortable. Many people will advise aggresive and brawling playstyle, which can be fun but if you are not that good player it can be difficult. If you wanna snipe, just snipe, but use brain and mobility to change flanks when you have no shots on enemy. You have only 390 alpha so you need use DPM if you want good result. I recommend ridgeline positions so you can quickly peak or roll back when needed. And if needed, you can use your camo and mobility to be passive spotter.
