Easily, we'd win outright. Though there would be casulties.
The first is the lack of large, dangerous animals. Sure, there's lots of powerful animals. Hippos, elephants, lions, tigers, rhinos, wolves, etc. But what use is a hippos' extending jaw with tusks against tank armour? A 120mm shell would turn a hippo to pink mist. It would blow an elephant simply in half.
We'd lose quite a few people who were outside of armour. A mass charge of elephants against a small group of soldiers, depending on the weaponry we had, probably would just get crushed and thrown each way. Elephants aren't as tough as people seem to make out, however. Remember, Alexander the great managed to kill hundreds of elephants in India with his army using bows and spears. We can put a 5.56mm NATO round through the skull of a charging elephant thirty times in about four seconds with most standard rifles, and that's a weak
If animals ambushed a squad, a single squad, then fair enough. But there is not an animal on the planet that can contend with us in force or stealth.
Then we look at insects. People on here saying there's so many of them are being ridiculous. We have the ability to drop napalm across a four hundred meter stretch of land which will be as wide as a football field. Nothing will survive that. That's also a small scale bomb, too. We have weaponry that can flatten entire cities, what use are exoskeletons going to be?
Granted, if a thousand ants get on you they'll eat you. Its been seen with large animals before it can happen to us, but they wont reach that close. We can outrun them, we can certainly kill them and even if there is 100 million of them to each human, we would kill them very, very easily.
Poisionous creatures would present more of a problem, but they still wouldn't beat us. We'd lose quite a few, but we wouldn't be beaten.
Flame weaponry would be our best bet here. Flamethrowers lost their effectiveness outside World War II. They weren't a practical weapon and the few systems that were still used in Vietnam were the same as they were in World War II. Today, however, we can rack up a system on armoured vehicles that projects a lengthier flame and its hotter. We also have white phospherous and napalm, which we can drop in more then ample amounts to destroy masses of insects.
Birds, pfft. In mass numbers they'd peak and claw at us, but its not enough. People would be wearing goggles and helmets, these are easily able to protect against beaks and claws. Then, at that range, just open up on them. Flames would also be helpful here, aided by explosives and rapid fire weaponry.
In the ocean, there's nothing to harm us. If we got off the ships our out the Subs, then yeah, inside there's no issue. I'd just use a Destroyer's forward 80mm to pop rounds off at large sea animals close to the surface and depth charges for everything else.
We wouldn't lose the sea, there's nothing there to harm us. And again, flames and explosives will annihalate insects.
Refer to above. How do you figure birds would take us? Those two meter tall Terror Birds that use to bumble around North America a few thousand years ago are dead, they are the only things that would present a threat. Smaller birds in larger numbers don't have the beaks nor claws to damage us on mass. Besides, even if they did, we'd just lock ourselves in armoured vehicles.
Again, refer to above. They have the numbers, but they aren't intelligent nor do they possess weaponry that we do. We can outthink, out shoot and definitely out perform them.
