Each robot is at the D-rank; this way, command can produce a lot of them with as little resources as possible. But he doesn't think that D-rank is weak. After all, he was D-rank when the invasion started.
He expected that they would be used for more important things than chopping down trees. So he was astounded that Command would also ask the soldiers to join in chopping down trees. Not only that, there is a reward for each tree they chop down.
He said to Wrath, "Don't you think this absurd?"
Wrath didn't share his outlook on the matter. She shook her head and said, "This is war. Nothing is absurd. There has to be a reason why Command had prioritized eliminating the trees. Maybe they have found a hidden strategic use for them, or they want to eliminate them to prevent the elves from using them."
