Fair, but I should say that both Guards and Shocks enter the field with better durability, and already mostly capable of fulfilling their AI (Shocks) or AT(Guards) capability without upgrade. Obviously the Guards can have DPs added, but they'll still have their AT rifles.
Still, CP2 is better than CP3, and I'd be happy to have that, at least. Would coincide with the M2HB drop.
I do think CP1 is better thematically, however, and I doubt the impact of Paratroopers at that stage would be as large as Shocks or Guards, at least without being upgraded.
Paras however can come into the field immediately and reinforce anywhere (including crewed weapons) so it's a bit of a trade off.
Tbh I'd rather airborne stats and vet get shuffled around and dropped to 2 cp than 1 cp as is. Could start at something like 0.9 RA and sprinkle their bonuses through the other vet levels.
I do agree that accessibility is an issue.
