Imperial guard woman

This picture is not possible in the Warhammer 40,000 universe, because the imperial laws don´t allow women in the imperial guard. The only women with permission to fight for the emperor are the women who belong to the sisters of battle.
In short, guardswomen or space marines women don´t exist in the Warhammer 40k universe. Remember, the implant that transform a human in a Space Marine, can grow up in males only, that´s why there are no space marine women.
If you see drawings like this, that show a woman with imperial guard uniform or space marine armor, is not possible, that will be a heresy according imperial laws.
In the case of the brave woman in my drawing, It´s likely that the space marine behind her, killed her when he saw her.
It´s sad but these are the rules in the 40,000 century.
