4e Mechanics & Rules Discussion

[Raellus]

I may have already asked this question, but it's been almost a year since I've played the game, so...

Can a PC Help another on an opposed Recon roll for a Group Ambush situation?

Here's the situation: I've got two PCs trying to get into a position to observe an enemy POW camp (and eventually, attack the guards). Since they are trying to get into an OP without being detected by the enemy sentries, I assume that I need to follow the rules for Group Ambush, which involves making opposed skill rolls.

One PC has INT A and Recon C, the other has INT B and Recon C. According to the Group Ambush rules, I have to roll for the PC with the lower Recon skill level. Both PCs have Recon C, but I assume that I should then use the lower of the two Ability scores to determine which PC rolls. Is that correct?

The two PCs already have favorable modifiers (+2 total) for distance (200m) and terrain (forest), but I would like to increase the odds of success by having the PC with the higher Recon skill Help the PC with the lower skill level, thereby adding another +1 modifier to the Group Ambush roll. Is that possible/correct? I don't see anything in the rules saying otherwise but I'd like to make sure I didn't miss- or misinterpret- anything.
