Answer: True
Explanation:
According to Mary Kaldor, a key differences between the guerrilla tactics that the revolutionaries used and the ones that the new warriors used is through the way that they control their territory.
Apart from the use of the regular military tactics by the revolutionaries, they also attempted to gain control of their territory through the use of popular ideologies so that the local support van be gained.
This is quite different from the new warriors who borrowed their tactics from the government counter insurgency units. The new warriors drove out possible opponents through the use of extreme violence, conspicuous atrocities, murder and genocide.
Therefore, the correct option is true.
