If I have to hear "Re-engage" one more time...
Another one to hunt for good enemy RNG. This is probably close to the best, but I swear I've gotten an even better one with only 2 groups of T-72s - the left one and one coming straight at you from the bottom of the hill. But even with this one here, some better luck/skill with the gun could have saved some time... probably. The airstrike taking out the two last T-72s at once saved a lot already, so unless I would have been able to get all of them before CAS, it wouldn't have mattered. But I am pretty confident this can be improved - you just have to get lucky. Not just with the main groups, but also the BRDMs and ATGMs. Sometimes you can even get 2 ATGM spawns! Guessing the right ATGM spot for the arty seems pretty vital for a comparable time.
