During the desert campaign in the 3. scenario there is one additional victory condition:

Kill 5 units in the first 3 turns.

OK!;but, how can I kill 5 units, when only 4 enemy units attack me during the last 3 turns and then it's "failed!"

Some of teh achievenments may be almost impossible. Someone will find a way to do it

This one is certainly possible but you have to launch a little counter attack yourself to wrap up the infantry of the first attack wave. Bren carriers are useful for that, but it'll leave them exposed for a turn or two, so it's not without risk.
