Bitter

I adore this mod but I keep failing mission 5 in part one, been failing about 2-3 times a week for the past month. I tried to edit the starting team to give me a couple more units to make it a little easier in the beginning but I must be doing something wrong. I'm really bad at timed missions and end up with about 30 minutes left, and then my mastermind gets destroyed by a group of infantry, my tanks get blown by a tank destroyer, the sniper kills the engineer I need, etc. A novel way to fail each week. I really want to get past this mission and move onto the rest, I've loved the others so far. I don't mind failing a few times at the start to figure out what's going on but being 30 minutes in and failing each time has been disheartening. Saves aren't helping me much since each time I got back a save or back a few saves I'm still down on time and fail in a different way. How do I edit the starting units? I extracted the sov05umd.map and edited starting time, deleted the sov05umd from the mix, inserted my edited map, then when I start the mission it gives me the same starting units. I should have an extra tank and extra gatling, 3 of each, but I just have the mission standard 2 of each. What am I doing wrong?
