Optics, CVS, or binocs?

Draschel: AMX13 105 should be played as a mini-bat chat. An ambusher, clipper. There are other light tanks which do scouting and sight lines better, but there aren't light tanks which do ambushing like 13 105.If you have an excellent 5-perk crew, where your commander has recon & situational awareness, +BIA and using ventilation in % boosting slot, with a ventilation directive, you are looking at 452+m VR. Which should be enough VR for an ambusher tank. This gives you considerably better gun control, and frees up equipment slots that you can run a choice of rotation mechanism, stabilizer, exhaust that again make you far more dangerous a lurker. If you play 13 105 as a scouting first tank, loading up on optics / CVS you are handicapped from the start, because others like Manti / wagen / T100LT / EBR will do it far better than you. But because you can lay down impressive ambusher burst of 3x390 damage, which other light tanks cannot do, it is better to play your unique tank with the better odds. Be a mini-bat chat.
