Im working at brigade level and its given me a new perspective

My whole career I worked at company level. Now im working at brigade. My biggest pet peeve is getting answers. I feel like im a CSI detective. Every day people ignore emails, teams, don't pick up their phone, etc. Talking to people face to face is the best option, its harder for them to weasle out of something. But you gotta catch them in their office first. This goes for civilians and soldiers. So much miscommunication too and what should take 10 minutes takes 10 hours.
