FROM: Central Defensive Strategy Post of Mars
TO: ALL ALL ALL
TOPIC: Counter Earth-spying mimicry and methane gas
TEXT: From last dissasemblies of captured earthians spying devices (codenames Phobos 1, 2, Mars Climate Orbiter and Mars Polar Lander) we believe that earthians are or soon will be able to detect methane gas produced by our units. Therefore Central Defensive Strategy Post of Mars decided the following:
1) Increase HID CON*) state to level 2.
2) Thus strictly forbid any non spacesuit-protected units to move on the opened surface of Mars (anybody, including child units, anywhere, no exclusions).
3) Order special chemical units to remove any traces of methan gas from the atmosphere over the opened surface of Mars ASAP.
*) HID CON = shortcut for the martians units Hiding Condition (MartianLeakes comment):
Level 5 - normal martian life status
Level 4 - no martians units are allowed to appear in the sighting field of cameras on the earth origin devices
Level 3 - no martians units are allowed to appear in the 5 km circle area around earth origin devices; any signs of intelligent life (and any life in fact) must be preemptively removed from the expected direction of earth origin devices movement, while any units on this task must wear appropriate mimicry suits.
Level 2 - all activities are suppressed except of deep inside caverns of Mars; special units are allowed to monitor earthians activities only in the special spacesuits.
Level 1 - we are doomed; remember indians in the intercepted earthians video transmittions and defend bravely untill the last stand
