I have doubts, that on the ground, robots are all superior to humans.
Clearly at the moment they are not though robotic warfare is developing at a rapid pace.

For example, one futuristic weapon is EMP, that destroys delicate electronics. And it is already under testing.
We can already do this with nuclear devices and whilst there has been extensive research into non-nuclear electromagnetic pulse (NNEMP) weapons none have ever been developed to the point where they can be usefully deployed. Either way however shielding from EMP has been around for decades, I'm given to understand your average off-the-shelf military equipment is shielded to a certain extent. If it began to be a problem e.g. if country's did start manufacturing useful NNEMPs then I'm sure shielding, redesign and tactics would be developed to compensate.

Also there can be quite difficult environments on the surface, the robots have to be expensive.
Yesterday's high-tech is tomorrow's cracker toy. Regarding difficulty on the surface I recall reading an article a few years back on the advance in collaboration and swarm intelligence in robots. It detailed examples of a UGV that had to navigate across a field full of ditches, mounds, bushes, fences etc. It did so by deploying a mini-UAV from it's roof that flew around and mapped the area, helping the UGV create a route.

In future, i think, we will mostly have to deal with terrorism and urban warfare, and many cases, immediate human level decision making should be needed.
Both of those could be supplemented by robotics and infact already are;

And in terms of fighting in buildings it's not that difficult to envision something like
this supported by a team of drones like
this? In terms of immediate decision making you can approach that by improving the software running it, including humans in the loop and mitigating the cost of mistakes. An example of the latter could be to fit the drones with non/less-lethal weapons in case they target innocents.

Other futuristic weapons are lasers, rail or coilguns, particle cannons.
Lasers are still weak, they can serve anti-missile purposes by blinding or overheating them. A railgun was quite powerful, but erodes quickly. I don't know any details of particle weapons.
Whilst there has been development in laser weaponry examples like the Boeing
YAL-1 project show that the technology has a way to go yet until it's viable. Having said that there are various continuing projects such as the
US navy FEL. Along similar lines railgun's are also
under development for ships.
Particle beams I also don't know much about other than the fact that there doesn't seem to be much development there.
