Interesting intelligence on Hezbollah:
"Hizbullah fighters were also found to be using special thermal suits that retained their body heat and curtailed IDF attempts to discover them at night."

In reference to your night versus day rocket firing of about two days ago. Saw something on link that conservative poet just posted:
"Hizbullah fighters were also found to be using special thermal suits that retained their body heat and curtailed IDF attempts to discover them at night."
So they may not be firing at night, but they are sure scurrying around, it seems.
