Don't spread the panic! Colonel Markov's suicide note is to be kept under wraps, I'm classifying it as "Top Secret". Nobody except for us three is to know if his last "orders", which are null and void anyway, as Col. Markov killed himself to avoid bearing responsibility for carrying those orders out. Directive 01 is to be strictly observed, the radio silence stands. The War is still going on, and we are soldiers. Even if we are to follow those treacherous "orders", we don't have the manpower or transport required to undertake a thousand-kilometer journey.
Lieutenant-Colonel R.V. Novikov,
Acting Commander of "Caspian-1" Satellite Communications Center
