I tried five Objectives, and GR stopped working when launching the mission. Went back to four Objectives and created another Objective [under Tags, the only way I can see to create extra objectives, noting you cannot add descriptive text there], then wrote the script to remove one of the original four [thinking a limitation maybe only having a maximum of four 'live' objectives], and replace with the extra 'Tag created' Objective. As soon as the script called that extra Objective, GR stopped working.
Combining multiple requirements to satisfy one Objective is straightforward to code (can assist if there is a need); which means you could get quite creative (say, like having to achieve those requirements in a given order).
I think it is correct you can have only four objectives but as you suggest combining two into one objective probably will work.
I had not played the mission in a long time. It is good but can be even better with some additional editing.
I tried RussiaGhost's edit and the enemy RPG man always tried to shoot the N. Bradley at the house.
It was difficult to kill the RPG man before he took out the N Bradley.
And thanks ,Wombat, to try my own M14 mission ...It's possible to make an alternate road for the North Bradley , but better , i think ,like i said to RussiaGhost , to plan that the two tanks start at the same place ,split, and after , in place of a long run to the camp ,wait at a place a little ahead ...need to add one more path each (4 for north and 3 for south). It"s can be interresting , in case of RPG risk to recon , before assault, with the tanks in safe place.
I don't succeed to add more than 4 objectives ( it's seems not possible) but only to have 2 objectives (conditions to) in one. In example ,the Centcom=rmx03= Dingo's Lair have that "kill aa + rescue pilot" !
I agree that the Bradley's going to the camp (safe !) will be challenging .
