Well, the bottom line is that as well as happened in Beirut (where I was present) and Zarajewo the snipers are the main force of this battle (at least in Sirte) as far as I can gather from friends and news reports: Roughly 70% of troops of both sides are dedicacted "snipers/sharpshooters", the surviving ones count between 5-10 enemy KIAs each )per paior, both sides operate in 2 man teams). Tank main guns rounds (and neither RPGs/Mortars) are not a general option in Sirte right now.
There was an interesting article in Spanish "El Mundo " about this today, but as its 1:20 in the morning here and my night ends at 0500 I will eleaborate with the transaltion (probably) tomorrow.
