It dawned on him somewhere between when Heero had signed off and Tech had responded that he was on stand-by, that old habits died hard.

General indeed, kreking, kriff, sithspit. Tech may have witnessed Ben running his hand up and down across his face, but by the time Heero arrived the older man had settled himself back to calm. A calm that took another blow as he realized that Heero was a very young man.

No younger than you were when you went flying off to ... Obi-Wan ruthlessly jettisoned the lot of it with a short breath and set his face into a serene neutrality. Shifting so he could whisper, yet have his voice carry, he motioned towards where Tech was waiting, speaking with the comm on so the clone commando could participate in the conversation.

"Six in the building now. I'm going in main door, Tech is taking the opposite window. He can jam signals but will also be neutralizing any who try to go for any sort of alarm or signal. Come in behind me, or support Tech?"

There could also be an option C that Obi-Wan wasn't considering at the moment, and if Heero told the old man to shove it and went to do his own thing; Obi-Wan would respect that.
