The 2- , means it was the second of two Battalions that made up the 108th. Also I think the 1 before the HQ41 is a roman numeral I which as
Scar59 posted stands for infantry. The HQ41 also means that your MV was from the Headquarters of that battalion and 41 is where it falls in the march order. Which btw does not mean there were 40 MV's before this. The last unit I was in mine was 24 and the next ones in line was 31, 32, 33, 34, then jumped to the 50's
So your MV was with the headquarters of the 2nd Battalion, 108th Infantry, headquartered in
Utica, which is part of the
27th Infantry Brigade Combat Team and has companies and detachments stationed in ten Upstate New York towns.
