Alter Schwede!
The Strv-122 is a Leo2A% with upgraded roof armour, mine protection, and some minor chnages, it also features different sights in GAS, and different ammunition. no bad choice. Only the spanish versions of the Leo2 are more heavily armoured - they are said to even withstand ICM.
You will not always stick to the two scenarios you currently deal with, Recon and Byto. ReM had good advise with his hint on splitting up platoon. Ypou could edit the mission and make it a platoon of four, then splitting it into pairs, having your wingman traling behind in ehecelon or column and formation distance set to "wide", the the leading tank is not alone if he gets into trouble nevertheless will be the one facing new challenges first, most often. Then you use both sections to overwatch your general advance, which is a tactcic you really MUST adapt to if you want to survive in SBP. One sets up guard, the other unit from the rear advances, makes the new fonrtline, switches to guard, and the the other advances.
If you are patriotic about sweden, the Strv-122 can be nicely accompanied later on with the Swedish CV-9040 B/C.
And then I would urge you to start learning to fight with GPS gone, stabilization gone, and turret mode switched to "off". You will get damage din other scenarios, and often your 100% okay status will not last long in battle. If then you do not have some experience in how to use the GAS sights to estimate distances and add lead manually, you're cold meat. Also, it adds tension and excitement, also hectic and drama
Fighting from GAS is really a challenge, and get be very tense.
In both scenarios a major factor is beign ignroed: artillery. Very often you will come under artillery fire if you stay in a position too long and the enemy has seen you there. Yoiu NEED to make it a common procedure of yours to cinstantly relocate after a minute or less, to avoid incoming HE or worse: ICM. ICM barrages often will kill you, or do major damage and disable crew members. Three hotkeys you should have - amongst others - on your input device: popping smoke, button up, and closing the armour shield for the GPS.
when you are under small arms fire or engaged in urban terrain, you may want to consider to keep your GPS closed anyway, to protect it from getting dmaaged by small callibre fire, and stick with the GAS anyway. Set it to battlesight range. You then must not worry about wether or not the gun tube has clear line of sight to the target - if you see it in GAS and sight is not blocked, in the M1 sight never will be blöocked indeed, and in the Leo-2A5 most often not (the new Leos have the GAS optics no longer attached to the gun tube's elevation like the A4, but on the roof as well).
So as much fun a single tank stalking may be, take care that you do not get used to flawed behavior that way, and learn wrong tactics. On a modern battlefield, one tank alone - is nothing. Only teams of forces prevail. Consider your units to be pieces in chess, and move them on the board to strong positions. Sometimes one by one. Sometimes simultaneously. It depends.
And never underestimate infantry close to you, and flanking. The Russian'S latest Panzerfausts and the German PF-III can kill you, no matter your tank. eventually I even got killed by frontal shots, at least I received major damage and crew losses.
