My first time as SO marines were defending hydro in LV, a synth gives me OB coordinates, i input them in the console and fire it, a few seconds later i hear an ob doomed the entire operation by hitting EXACTLY IN THE MIDDLE OF HYDRO, killing about 24 men (we had k/d back then).
Turns out i mixed lat and long and also put the numbers wrong. funny thing is i dont remember being bwoinked for that, i probably got noted tho.
Was brigged shortly after that, managed to evac after xenos came up.
