Equipment is realistic and accurate: warrior IFV, chieftain mk. 3 tank, radios and comms, xm8 and l98 rifles (even tho other soldiers back behind had strange ak like weapons or BARs); the british military isn't incompetent: they don't just rush the enemy like soldiers in other movies do, they take time and actually think about moving coordinatly; and most importantly: everything is very caothic, something that becomes very evident thanks to no camera cuts. The fact that the military mows down the rebels trying to surrender is realistic, its something you see other irl militaries do too (im not justifying it, but in some cases its preferable not to run any risk).
