We didn't see the thermal until we were overseas. Even then there was only one or two, so only a few people were up to speed on it. Nice piece of kit from what I saw on my brief time with it. As for the IR Laser (PAQ-4) and the MNVGs, we had them during work-up and the troops got to work with them. The only problem was the lack of range time with them. Most of the guys in my Pl were fairly well versed in their useage having used them previously overseas, but for some of the new guys they just didn't get a chance to use them enough till we got overseas.
The suppressors were only on the C7CTs, and since we never had one in the Pl I'll defer that question to Kev.
