Deployables. The Idea is simple really a crate that can be drop from orbit pick up by a unit and places this Deployable and the Turret or Other is place on the battle field.

This has been done.
Try Darkstorm. Try the variety of other mods that have done this.

Darkstorm you say? i've got that mod and it has nothing what so ever reguarding that subject and for this Variety of other mods you've spoken i've check the Search a Great deal of many time and came up with nothing so...

In craft, there are two deployable turrets.

He wants a turret which you can deploy by dropping it from an actors inventory, all cod sentry gun style.

DragonXp You hit the nail on the head. But as all items that you buy it will have to come by Dropship or other means.

In that case, the answer is that it is entirely possible, but as far as I can recall no such device has yet been made. A variety of similar devices have been made, but the closest thing would be the Turret Stand.

Then Since nothing like it has been created then we better created one.
