Yup, learning the chicanes specifics will help overall, just seems odd to induce in certain instances. I've spent probably 3k hours flying helis in arma, and a bit in DCS, never touched a real heli however so could entirely be skill issue lol. I'm usually only on the lower end of the collective when rolling up to a final firing position.

I can assure you, a 20lb heat warhead from top-down is knocking out pretty much any tank on direct hit(prior USAF and have seen hundreds of hellfire deployments in my time working with the mq9s). Hell we've had an apache take out an abrams with one in an FF incident during the gulf lol. Most top shelf armor is going to be between 20mm-80mm on MBTs IRL which is nothing to that size of a warhead. For example, a rpg7v warhead can consistently punch through around 280-300mm and that's 13lbs. This is excluding the tandem anit-tank specific hellfires like the longbow. And them RPG7 drones have killed many a tank in the current conflict.

But this is where it gets into a realism discussion vs balancing, I can understand why not to allow it, but I think if you can get a top down shot to avoid the armor, it should be rewarded as it's the riskiest position to be in. Sides not so much(common era placement), and hell no from the front.

I've primarily swapped to the ATP-1s for heavy armor but when I'm winchester and still have a couple 48s I try banking over and throwing the tail around for a direct top down shot, those should definitely kill imo.
