    We do not have centuries of data about the extent of Martian ice caps, which vary considerably seasonally. Visual observations of planet from the Earth's surface are extremely difficult and give low resolution fuzzy images, and until well into the 20th century had to be sketched by hand. Remember those non-existent canals on Mars? That was typical for attempts at interpreting blurry indistinct features on the tiny visible orb.

    To have any hope of estimating Martian ice cap coverage at even one point in time you need at least sufficient accurate observational data to draw up a map of Mars. The first such was not prepared until 1840, and one with sufficiently quality for any hope of a quantitative estimate of ice cap coverage was not until the opposition of 1887-1891. In fact good data about Martian ice caps only became available in the age of space probes.

These features create a weapon that can accurately fire a large volume of highly lethal rounds (at medium to short range) as fast the trigger can be pulled. In other words it is optimized for killing a large number of people in a very short time who are not far away. An optimized, purpose designed massacre weapon.

    It doesn't matter what they look like, any weapon matching these characteristics is an assault rifle. They are a poor choice for hunting, the cartridges are not powerful enough for clean kills of large game, they are not accurate enough for long range shots, and any hunter that can't take his target in 2-3 rounds shouldn't be hunting.
