You all realize the counter to armed UAV's and dominant battlefield equipment like the Abrams tanks?
Enemy goes low tech. They go among the dense populations. You put your assets up against children's hospitals and mosques and residential apartments. Been the trend since Somalia and Bosnia. So, if you *do* hit them, you wind up with large numbers of civilian casualties.... collateral damage.... lot's of pictures on the internet and in the news of dead, burnt babies......which works against you in the world diplomatic and public relations arenas as well as at home in domestic politics.
Worst kind of fighting there is is urban fighting in someone else's city. Not the place you can do aerial bombardment or operate MBT's very well. It's the kind of fighting that takes more troops on the ground and MRAP vehicles. There's a lot of tech being developed....finally.... for that arena too.
