A Centurions surge might work, but it depends on many factors
What is the mission is the first factor
How is the enemy made up?
What level of Veteran is the enemy and what are your pilots?
Ground
If the terrain is urban, your veteran pilots, the green enemy, you may have a chance to win
If it's open terrain and the pilots' experience level is balanced and they have a couple of mechs flanking the enemy, I don't think they have too many Chances, they are moderately slow and they don't have jumpjets.
