You've saved me a headache!
I've been working on a scenario of the PAVN raid on the USAF/Mhong TACAN site 'Lima 85' (Pha-thi, Laos, 11th March 1968). I was having problems assigning victory hexes etc and I think your extra 'toys' could be the answer.
This, the largest ground combat loss by the USAF in the Vietnam War, is unusual in that the PAVN OOB is more complete than the USAF/Mhong one - due to the site being overrun.
Cheers
