clearly not highly trained, but maybe just desperate with limited options?
Wouldn't most people be a quivering wreck at such a near miss to having their head exploded?
have you lived in a warzone for years?
probably somewhat similar from living in the country to the city, all a bit of a shock then you get used to noise/busyness. make it more extreme and live in a country bombed by the west and other countries and your own people for years, you see lots of clips of these areas of the world where attacks happen/explosions happen and life is just going on around it (it has to).
