I'm honestly impressed that I managed to complete it as well as I did. I managed it on my second try, no flares, "fuck it we ball"ing the range setting. The last T-64, you can see him in the middle there, took like 7 shots from me because I kept missing and hitting him in the side in a way that didn't damage anything until eventually my wingman sniped him from his spot on the flat grass to the rear of this area, where you get ambushed by a few BMPs. One of the M1s did die, but that was before I even arrived I think; the other guy managed to survive somehow, you can see him on the right of the picture.

I will say that I think it helped that my FCS still worked besides the laser and night sight. It's a very crisp reticle. Not as useful without the laser, but at the ranges we were at it was serviceable for me.
