ITC is the Intensive Training Cycle Gunnar and his unit are in the midst of currently. It's an 8 week program that should help them to prepare for the next deployment. Basically they go spend a lot of time out "in the field" doing training exercises etc. This is what it mostly looks like:
The guys have been spending several nights at a stretch out in the field and have only been able to come in for a couple of nights here and there and then off they go back to the field.
Gunnar is in a slightly different situation as the armorer. He is responsible for all the weapons in his company and that's a pretty big deal. He ends up going out to the field, spending a few hours then someone realizes they'd prefer to have him back in the arms room. Here's the funny part. Even though he's not sleeping out in the field with the others, they make him sleep in the arms room.
This morning Gunnar left and said he actually might be sleeping in the field, not the arms room this week. Who knows if it will actually happen, but I think I'd prefer the outdoors to the concrete floor!
