Shan,

Don is right, don't include ammo trucks in combat formations (above all infantry or armor, I don't know about artillery), since in IA command (as far as I remember, maybe it has been corrected in the latest versions) the trucks will attack with the rest of the formation, and they are generally faster.
And you don't want to end up with exploding ammo trucks on your frontline...

As for command sections, I have run into this problem in the French OOB as well. IMHO they are to be included if you want a realistic OOB, but you can make them inconspicuous enough and more resilient.
EG here you can take the PzGr platoon HQ (and XO) group, add in the Carl Gustav team and the sniper, and you'll end up with two identical "support sections" (or just give them the same name as the normal section), with 2+4+1=7 men each and a decent weapon layout of AUG/sniper/CG/grenade.
You lose some flexibility (e.g. no separate sniper you can hide behind the troops) but you have much less chance that your platoon HQ will be singled out and wiped out on turn 2.
Other question, while I'm at it (may have a relation with that problem too): what is the level of training of the platoon-level snipers? Are they top-notch infiltration-capable snipers British-style or just trained marksmen with good rifles? In the second case you have even more reason to include them in the infantry units.
