After the Riksdag decision, it emerged that the tanks at the regiment's brigade were in such good condition that they were judged to have a lifetime until the mid-1980s.

As a result, the decommissioning decision was revised, that is to say, that instead of during an interim period placing armored training to Strängnäs, it remained in Enköping until 1980.

This organizational change resulted in the Blue Brigade being able to add an entire battalion each year.

With that, mechanized infantry units in the Blue Brigade came to be trained directly in the Göta Life Guards (P 1).

During the Defense Act of 1977, opportunities were created to renovate and extend the lifetime of the brigade's tanks.
