Also we should realise that these weapons really are not that effective against soldiers.

Because of soldiers' protective gear? Will all our troops in the region be wearing such gear?

Because of soldiers' protective gear?
yes amoung other reasons. Environmental conditions also can also restrict there use(rain, wind etc.)

Will all our troops in the region be wearing such gear?
From what I've seen everyone has them on their persons at all times.
