Absolutely, kit like BlueForce trackers (BFT) make things much easier. However, it's not bulletproof. I understand BFT doesn't work as well in built-up urban areas (i.e. cities). And the human factor will always be around, as will the fog of war.
Black Hawk Down is a great demonstration of this. Despite cutting edge C3I (
https://en.wikipedia.org/wiki/C4ISTAR), US forces had hell of a time trying to communicate clearly and effectively to deal with crises as they popped up. Questions and issues that made Somalia 1993 so tricky: multiple downed helicopters, no proper plan or assets in place to medivac the high unexpected number of casualties, figuring out where the mobs of fighters are turning up, dealing with the repercussions of staying in the area of operations way beyond the mission's expected timeframe, and just where exactly all the friendlies are positioned?
Just because you have the tech doesn't mean it'll work perfectly each and every time. The US forces in Mogadishu had AWACS overhead (read: aerial surveillance) but there was plenty of communications breakdowns in the intelligence loop from the airplane to the tactical operations centre (TOC) to the guys who needed the information on the ground.
Mechanically, the Assess move is just as significant as it is in other time periods:
"Great, you rolled a 8. The BFT on your Humvee's dashboard shows Hitman Three-One about a klick north, holding up by the hotel. But you're getting conflicting reports over the comms that Hitman Three-One is actually west of your position, in contact with Iraqis near that ridgeline. What do you do?"
"TOC says they'll get back to you about about the friendly convoy's location in five mikes. They urge you to stay frosty and sit tight. But looking out across the street, the mobs are getting restless. Do you stick, or move?"

It's really perfect for a game of The Regiment, with lots of maps laying around and cool special forces ninjas destroying things with drone custom moves ("Operator" playbook).
