The 'Black Hawk Down' mission everyone is proposing is what happens after the Rangers and Deltas are given the go-code Irene in the movie, I presume.
Let's break that down into details:
Here's how many vehicles and troops you'll need
- You need several ( think there are four to six in the movie) UH-60 Blackhawks (or are they MH-60's?) loaded with Ranger Chalks. That is four vehicles, with at least three people per vehicle as crew if you want it to be realistic (pilot, copilot, gunner). 4 x 3 = 12 people just for driving the blackhawks around. Then 6 people as cargo, 4 x 6 = 24, 12 + 24 = 36 people just in the blackhawks.
- You need several AH-6 littlebirds and MH-6 littlebirds, I think somewhere along the lines of four AH-6's and four MH-6's, with two people per chopper as crew (pilot, copilot on the MH-6's and pilot, gunner on the AH-6's). 8 x 2 = 16. Then we have four deltas on each of the MH-6's. 4 x 4 = 16, 16 + 16 = 32 people just for the littlebirds.
- You need the HMMWV convoy(s). Which consists of about two 5t trucks with at least one guy driving, so that's two people. Then you need about six HMMWV's armed with .50 cals, each with four people in it. (Driver, Gunner, 'co'driver and just an Operator) That is 2 x 1 = 2 for the 5ts, then 6 x 4 = 24 for the HMMWV's, that gives us 26 people just to operate the HMMWV convoy(s).
- Now on to the enemy forces. You'll need at least fifty Habr Gedir militia-men to simulate the actual BHD-mission. Maybe not all on screen at once, but you'll still need them. That is 50 AI controlled troops.
- You'll want them to get around as well, so put in about six Technicals at the very least, each with a driver and a gunner. 6 x 2 = 12 people to operate the enemy Technicals.
- Habr Gedir officials (the one they are snatching), in the movie they snatched about thirty people, you could lower this to twenty and still get the proper effect. But 20 people as the target.
That is 36 + 32 + 26 + 50 + 12 + 20 = 176 AI controlled troops. (Well, 175 AI controlled, one player controlled)
Not only is that a stress on OFP, because it needs to draw the soldiers, and keep track of them using the CPU and the memory.
Then to that we add vehicles. 4 + 8 + 8 + 6 = 26 vehicles.
Vehicles which are harder for the OFP engine to keep track of, because they consist of more polygons, more selections, more proxies.
So that will drain more CPU, more memory and more GPU power.
To this we add the huge city terrain which we'll need, which will be damned hard to construct and get to run well.
I'm running a good system (AMD XP 2000+ 1.66GHz, 256mb DDR, GF4MX440) and I notice a hit on the performance when I enter say Petrovice. That is just outside the houses, but it still adds to what the OFP engine and my computer has to deal with.
So making a city which simulates Mogadishu would not be a good idea, because only those with enough money to stay at the leading edge would even be able to play it.
Then we'll need to do a lot of CQB, and, like Evis said, this is not one of OFP's strongpoints.
Then you'd need to come up with a way of making the AI drivers drive exactly where you wanted them. That goes for the 5ts, HMMWV's, Blackhawks, Littlebirds and Technicals.
Because you know how stupid the AI is when it gets into a town whilst on the ground, and the choppers would either crash into eachother or into a house if you didn't keep an eye on them.
This mission is not
suitable for OFP. You could make heavy alterations to the mission, but then it wouldn't be Black Hawk Down anymore, so what would be the point?
I'm not trying to rain on anybody's parade, but you shouldn't pursuit near impossible goals either.
