Day after day

A person puts on tan combat boots on a concrete floor, then a hand pours liquid from a jar into a mug containing a dark substance, followed by a man in a green shirt and black pants performing a pull-up on a horizontal bar outdoors, then a soldier in camouflage and a balaclava aims a rifle, then a person in a green jacket looks out from a moving vehicle down a dirt road, and finally a person in camouflage holds an open book with black and white photographs and text.
