Lots of things have changed in 40 years.
I have never heard of scenario 1 ever occurring. Not saying it hasn’t, but it’s nothing I’ve been privy to hear about. I know of many Marines awarded Purple Hearts without corresponding CARs if that’s anything worth noting, and that’s always struck me as odd. Most CARs I have seen awarded have been for direct enemy engagement regardless of MOS. Combat jump devices are a little bit of different story due to the knowingly placing yourself into an in extremis situation. As with most things - right time, right place, and right job. Earning a CIB or CAR is definitely noteworthy, but It’s not something I would particularly swoon over when it comes to career accomplishments.
You’re right, it has changed. I just looked up the criteria in the Awards Manual. It says:
“The principal eligibility criterion is, regardless of military occupational specialty or rating, the individual must have rendered satisfactory performance under enemy fire while actively participating in a ground or surface engagement. Neither service in a combat area nor being awarded the Purple Heart Medal automatically makes a service member eligible for the Combat Action Ribbon (CR).”
And
“Direct exposure to the detonation of an
Improvised Explosive Device (IED) used by an enemy, with or without the immediate presence of enemy forces, constitutes active participation in a ground or surface engagement.”
So one instance makes one eligible. And the commander has a lot of leeway in saying what is direct exposure. Do you see the IED, mortar impact, etc. or are you inside the blast zone. @Sawnee’s example of a mortar round inside the FOB iOS a good example of the ambiguity in what defines direct exposure.
The CIB, on the other hand, requires:
“A soldier must be personally present and under fire while serving in an assigned infantry or Special Forces primary duty, in a unit engaged in active ground combat, to close with and destroy the enemy with direct fires.”
A CIB is not awarded for being exposed to an IED or a mortar round.
A CAB is probably the equivalent of the CAR as it is awarded to any Soldier who is personally present and actively engaging or being engaged by the enemy, and performing satisfactorily in accordance with the prescribed rules of engagement and there is no specific requirement for the enemy hostile contact to be direct.
The original proposal for the CAB was similar criteria as the CIB but it was for combat arms troops other than infantry. It got continuously watered down to include all Soldiers due to complaints about unfairness and exclusion by the non-combat arms MOSs.
The Combat Medical Badge is of similar prestige as the CIB as the CMB requires the Soldier to be a member of the Army Medical Department and assigned or attached to a ground combat arms unit which provides medical support during any period in which the unit was engaged in ground combat. The Soldier must be performing medical duties while simultaneously being engaged by the enemy. I personally think the CMB is more prestigious as the Soldier isn’t actively fighting but rather has to just “take it” while providing first aid to the wounded. Must wounded got wounded because they were more exposed to the enemy fire so the medic is probably more exposed too.
