Thanks for the responses!

OK - some results:

I tried the weapon with the above stats as:
1. a Class #2 secondary Inf weapon
2. a Class #13 ATGM
3. a Class #5 Light gun
4. a Class #3 Team weapon

I tried each of these 4 as:
1. slot 2 of a class #1 Infantry section
2. slot 1 of a class #2 Infantry AT
3. slot 1 of a class #206 Infantry ATGM
4. slot 1 of a class #208 Infantry RR
5. on a light vehicle as class #238 Lt MIFV
6. on a light vehicle as class #19 SP ATGM
7. on a light vehicle as class #39 SP Gun

I found the weapon seemed to work best as a ATGM (HE only) in the hands of none AT troops.
Set up like this I got the right graphic and sound FX, limited burst radius, etc that I feel the weapon should have.
I got what I thought seemed to feel right (again only my opinion) with the weapon set to ATGM (class #13) in the hands of a Inf RR team (#208).
It was woefully inadequate against decent bunkers, armoured vehicles etc, but reasonable against soft stuff and infantry. I guess what you end up with is a very accurate, very visable(when it fires), low ammo and rate of fire HMG.
