So your plan is to put 120lb drawfs on these things, with no combat gear or personal arms and ammunition.
Having spent a long time in the army I know that one soldier in combat gear with water and ammo is going to be close to 300lb or at least 0ver 200lb. You cant send soldiers into the field without arms and ammo and water in combat gear.
These things are a crock, a strong gust of wind will knock those things over.
Any altitude over 50 feet they are going to show up on radar and with no protection in the form of any armor then one assault rifle will bring them down. Low flying helicopters that can carry 6 or 8 fully equipped soldiers are already in use and they have their own weapons for protection.
These things will be better used in parks and play areas for the rich back at home in the city.
