But check this out:

Under Advanced Weapon Systems
The 25mm airburst weapon system.

Like the Bazooka-man or flamethrower operator of the past who needed rifleman to provide for their protection,is this a step backward?
Mind you having a man who could put thermobaric rounds into the OPFOR's position out to 500meter's would be a real "nice thing"!
But what happens when I need to clear a block of houses?
What helps at 75m-500m could be a liability at >20m.
Why?

The Marines have purchased 9000 of the M-32 six-shot 40mm grenade launchers as of 11Jan 2006.
