On tv what is the name of second colonel who tried to catch A Team?

The second colonel who tried to catch The A-Team on the TV show was Colonel Decker, portrayed by actor Lance LeGault. He was introduced in the third season and became a recurring character.

Decker was a more relentless and ruthless antagonist compared to the original Colonel Lynch (played by Robert Vaughn). He was determined to bring the A-Team down and was often at odds with the authorities, who felt he was going too far.

While Decker appeared in several episodes, he never truly succeeded in capturing the A-Team.
