When all the "little" clones are on/the lunchbreak and you have to (wo)man the checkpoints to the "zone", despite being barely able to pick up people's passports let alone read them. On the plus side, it's easier to check the bottoms of the vehicles.
The idea behind this picture is, that the Emmas are hired as some kind of mercenary army to keep the peace in a demilitarized zone. They're discharging their mission dutyfully, despite not being the brightest bulbs on the shelf. Plus, being giant, beautiful ladies draws in a lot of... "tourists", which doesn't make their jobs easier.
