So the bog-standard regimental gear is 38 kg, including the probably-ditched (or put on the servitor) grav chute. I'm also pleased to note that the only ammo that looks to have weight is backpacks, and I don't see a listed weight for rations either.

As for grav-chutes, you never know, being able to leap off an elevated walkway and safely fall a few levels down-stack could be a life saver.

This is why we put enough 'chutes on the servitor for the PC team to go secure an elevator XD
