Patrolling a stretch of about 1 200km of dry desert across the Kalahari dunes in temperatures of up to 47C daily can be a daunting task.
"It takes dedication and shows loyalty to our country. We could all learn from the commitment shown by these men," said Safety and Security Minister Charles Nqakula here yesterday.
The minister was referring to the 40 SA Police Service (SAPS) members who have been deployed here on the border posts of Botswana, Namibia and South Africa.
This deployment is part of government's plans to shift border control from the defence force to the police, following government's completion of the SANDF/SAPS exit and entry strategy for 2004 to 2008.
The deployment commenced on 13 September, as Mr Nqakula explained, border control was the duty of the police as it involved crime prevention and combating which was not the function of the defence force.
Mr Nqakula had visited the men in their three units - Middelputs, Rietfontein and Nakop to inspect their working conditions and living arrangements.
They were developed there after a weeklong refresher course.
The course included understanding relevant legislation such as the Immigration Act, detection of impostors and smuggle techniques, crime threat analysis and driving 4X4 vehicles, suitable for desert areas.
Captain Miya, base commander for Middelputs, said their duties included checking for clues of illegal border crossing.
"The law states that people have to use the border gates. If we find people who are crossing illegally we arrest them," he explained.
The units have brand new air-conditioned tents as sleeping quarters and recreational facilities, complete with pool tables and TV sets. The 4X4 vehicles are also air-conditioned and have fridges.
The Middelputs unit patrols up to McCarthy's Rest and back along the Botswana border.
The unit from Rietfontein patrols the corner wedged between Botswana and Namibia, while the Nakop unit patrols the straight stretch of the border along the eastern side of Namibia.
Mr Nqakula expressed gratitude at how the men had adjusted to their environment, enduring scorching heat most of the time.
One of the members of the Middelputs unit, Samuel Ndwendwe from the East Rand in Gauteng, said that two-and-a-half months could feel extremely long under the hot temperatures.
"Unfortunately I have no control over the weather," Mr Nqakula joked later with the Nakop unit.
Currently there are no women in the deployed units, but Captain David Mbambo, section head of border police, said that future units would include women.
