Agree!My CO told me once that it wasn't the platoon leader's job to run the equipment but I always felt like I should at least know the basics and know what we expected the operator's to do. Can't rely on the platoon sargeant all the time.
I used to get kicked out of the motor pool by the PSG all the time. He viewed that as his domain. When we went to the field the platoon was mine. When you are fixing or replacing track on a tank, a crew level job, all 4 crew members should be there or the job just became 25% harder.
One of my tanks was a blade tank with an add on hydraulic dozer blade to prepare positions. The thinking was you engineers would be too busy and never around when needed. The hydraulic lines ran from the engine compartment under the hull to the blade. They often were torn off in normal operations and thus useless most of the time. The added weight in the front did make for a very stable firing platform though.
