Don't ask my why this popped into my head - maybe too many video games?  Anyway, I'm loving this series and bought up to X after I finished I although I had a delay in reading because II was very difficult to find (ordered used off of ebay).

Just started V and realized while finishing IV that I didn't recall the use of hand grenades by anyone in the fighting.  Just seems to me that they would have come in handy, particularly towards the end of IV in the caves, not to mention in the hatch of a tank in III.  If I'll see them later in the series just reply with a "wait one."
