They're like Paras, I am told, in a post where I point a finger at Paras and the fact that they arrive with only carbines, and then need to upgrade to one of their two weapon options.
Commandos gliders do arrive with all their men but they also arrive in a glider that takes the better part of a minute to finally sail around the sky, giving all the early warning an enemy commander could ever need. They, like shocks, are also strictly CQC only, while Falls and other elite infantry enjoy huge amounts long range firepower.
You are the only one understand. It's stupid when falls can just beat non-upgrade paratroopers at max range while being cheaper. They scale up extremely well with its long range fire power and vet. Simply CQC unit like commando and shocks are nowhere comparable. Thus, they need to sink some munition like paratroopers for their long range power.
