Tartare, you're clearly someone who has never experienced the 'destabilising' effect that tracer headed in your direction has on your focus.
On the other side of the coin, were I sitting quietly in a desert somewhere and I saw an angry-looking Sukhoi barreling towards me, would I like to find myself near a cute bells-and-whistles advanced MANPAD or an ancient ZPU 4?
I'll think I'll take the gun, thank you.
Really, when will you guys start to appreciate that what works wonderfully well fresh out the factory on a sanitized range somewhere is next to ******* useless in the real world of half-trained operators, humidity or dust and limited or no servicing facilities?
