Another con is their limited flight high, flight operation, and horrible steering. They are not that easy to repair either. The wires need to be calibrated perfectly, as wrong calibration might result in failure and loss of the plane. The weaponry is also hard to calibrate, as wrong calibration causes the machine gun to hit the propellor. Also, most modern bullets pack quite a punch, they can just tear of your entire wing in a few hits.
I am fully against rhino farming. It's yet another 'and this is why we must destroy them, mr. President/Prime minister/ dictator.' Just waiting to happen.
What, we are saving an near extinct species(no reason to shoot one whitout horn) and making a profit. Hell, we can even do the selling on the black market and then we'd be following standard procedures.
If we're going to have an airforce, I propose we hold on to our dirigibles, and invest in cheap interception technology. (A tight network of iron chains stops most rockets on a safe distance. And flak can stop fighters.) For fighters we use whatever we can get out hands on cheapily.
Dirgibles? Biplanes? We don't we just get foot operated helicopters and call it a day. Seriously, the most half-assed army on earth could finish off our airforce. Do yoiu know how many hand-operated SAMs there are? Enough that we wouldn't last very long.
I like the idea of vehicles, as we learned from Syria that aircraft can easily turn tides, but not ones that a random dude wit a home-made RPG could shoot down.
Corruption? Rebellions? Good. We can exploit both of those. All we need now is a reason that any rebels would want to listen to us. Anyone here from the Congo? Because as of right nw we are a bunch of foreigners attempting to take over their country. I doubt they'd appreciate it, no matter how much of a improvement it is.
