Too true! The Rangers get into fire-fights about once a month in one particular (enourmous) park. That is their lot. But the incidence needs to be increased as they've lost more than a hundred rhinos this year.
The use of MRs is hoped to achieve this; and to follow-up once the poachers gap it.
Flying time is onother big issue. MR teams will have to have a few machines for 'relief' purposes.
Definitive ID is not required, just need to find them using a few tricks, and then follow them. Early days yet!
I don't want to hog this thread on this subject, but thanks for all the input.
