Scottish border control post

It is expected that, after Scottish independence and the economic collapse of the rump UK, there will be serious refugee problems at the Scottish border. These control posts, armed with machine guns and rocket launchers, are being constructed to keep the starving English out. Facial recognition systems are in place trained to direct fire at former high-ranking English politicians who may be attempting to conceal themselves in the ragged tide of humanity: their names have not been revealed but I think we all know who they are.

There is considerable technology reuse from the Scottish Space Program.

PS: I am English, I fully expect to end my days under the fire of one of these towers.
