Hi members,
Plz. read the following paragraph & help me by answering the question at the end.Thanks.

"The use of Chemical toxins,however,has been less widespread.Their large-scale us was first made during the world war1,but in modern history the iraqi army has earned a notoriety in using poisenous gases against the Kurd guerrillas and Iranian army.
The Russians've also used toxic agents against Afghan Mujahideen & Chechen
freedom fighters.But the limited tactical usages remove them from the domain of environmental warfare to the area of chemical & biochemical warfare.
On the otherhand,the use of toxins in Indo-china by U.S.A is textbook example of environmental warfare.The Americans used herbicides to defoliate large areas of enemy controlled forests & vegetation, the effects of which're present till today."

I request u to tell me whether the particular names/nouns such as Iraqi Army,Kurds,Russians,Afghan Mujahideen,Chechens,Iranian U.S.A & Indo-china will be omitted or retained in the summary/precis?Thanks.
