Earth bag construction (sand and clay) techniques are increasingly seen as a useful alternative to conventional building in low environmental impact projects and I wonder if there are applications in expeditionary infrastructure construction, field defences, flood defence, mortar pits and non equipment bridging projects.

The system shown in the video from United Earth Builders can do 300 feet per hour.

There are other fabric tube filling devices on the market.

Nothing wrong with conventional sandbags of course, they are cheap and easy to use, crucially, not needing any mechanical plant, fuel or skilled labour.

But they are slow and inefficient.

The Army does have a number of BCB Sandbagger filling frames in service

But evidently, not enough, traffic cones can help though!

Improvisation in action but a quick look on Youtube would show how filling 6 sandbags at a time is childs play :)

If one is a little more serious about sandbag filling there are many systems awaiting nothing more than an MoD Purchase Order.
