I have now submitted my Tsavo SLASO mission, with a few hours to spare before the deadline:-

I enjoyed this map! IMHO Tsavo SLASO is easier than Storm SLASO. In fact, with a suitable route and a reasonable amount of luck you can get to the final battle with the Wraiths, skipping every fight, just by rushing through. You can drive all the way from the start right up to the first big tunnel barrier, and run from there onwards on foot.
With a good strategy, using vehicles, maintaining a safe distance, playing safe, every step of this mission is simple and reliable, and requires minimal skill and luck. In my video use Tyrant's 2.0 strategy, with some minor variations. I take my time at the fight before the first big road tunnel barrier, rather risk a sneaky win from the hilltop. I also usually board a Chopper at that point, for a few reasons -- it recharges your shields, a Chopper can get onto the other side of the broken bridge even if you don't have a grav lift, it's an easy way to kill the two brutes outside the tunnel that leads to the final area, etc.
Having said all of that, in the final area I accidentally lost my BR, and lost pretty much all my shields in a careless first assault on the wraith's gunner, and so had to proceed very cautiously from there.
