I looked a bit into this "Marjah", target of the ongoing "Operation Moshtarak". A German blog mentioned that there's some confusion about whether Marjah is a city or not.
It turns out that Marjah is an an agricultural development district with irrigation. There's no city, no town and barely something that could be called a village.
Most of it is simply a very subdivided green area in the vicinity of some similar areas. There's open, easily controlled terrain around it.

The names of settlements can be quite confusing in Afghanistan (close to Kunduz is a village that consists of three parts wide apart!) and there are locations with similar names, but this is confirmed to be the right location for the "battle".
By the way; there are some accusations in regard to reconnaissance / military intelligence in this Marjah action. It appears as if the object recce wasn't exemplary.
Such poor intelligence (if the report is true) would be understandable if Marjah was a remote mountain village - not so much given its real location.
I saw some news about the ongoing OP recently that suggested a prominent role of heliborne troop insertions. This is odd, as there's not that much helicopter transport capacity for the many, many necessary troops (the Marjah green area has a perimeter of about 50 km) and there's no real chance of operational surprise. The "offensive" was announced weeks in advance.
