Mr Blackard keeps time tight on a lot of his scenarios, I have not played any recently but there might be a good case for play testing & increasing the number of turns & putting timed objectives on at around 9-15.
Timed objectives are a very good addition which give you the need to hurry up.

Its up to you what the length is & in most cases adding a turn or 2 is fair enough, its just play balancing. Keep in mind some have become harder & some easier since they were designed due to changes in units etc.

If people do update them another thing to look at is just making some minor adjustments to deployment. A lot deploy the platoon leader to the front so just swap his position with the rear platoon unit. Saves spending the first turn with your platoon leader staying as is or even moving backwards to sort this.

63 is unwinnable its supposed to be, read 64s intro notes.
64 is still nigh on impossible, see if you can do better but what I did was send infantry forward, stick a vehicle over, see what fired & killed it. Then use your infantry to smoke so just engaging one or 2 targets & send the rest up.
Recon by death due to the time constraints.
