Vrusk on the battlefield?

i need some opinions on the Vrusks. Are they really suitable to battlefields? Can Vrusks 'get their head' down  when the bullets start firing? Can anyone see a role in which these beings would excel in?<br /><br />I'm not having a go at Vrusks, just trying to rationalise their participation in a battle. I just don't see them as frontline troops. Vehicles would have to be adapted to allow for the bigger body mass, making associated war machines less efficient, and more susceptable to being a battle casualty.<br />
