No no no... Commandos only need to be able to receive veterancy from the Lieutenant and Captain. Otherwise there's a risk of them becoming overpowered again.
Plus you don't nessasarly have to blob to use Commandos with Lieutenants. I give one squad their own Lieutenant and keep them in a separate control group while supporting them with my Infantry Sections in my main control group. The Infantry Sections would fire from cover while Commandos close in for the kill. This tactic is brilliant when you have captured an MG42 (Which would be my third control group).
Of course, I've been doing that with the change I'm suggesting when I merged YurdleTheTurtle's (A strategy moderator at GR.org) mod with Eastern Front.
As I recall from playing the closed beta of Opposing Fronts, there was once a bug that allowed Lieutenants to give their veterancy bonus to American Infantry (It might have effected Panzer Grenadiers as well, I'm not sure) in range too. So I think Relic fixed that problem by making the aura affect builder type units rather than soldier/infantry types. Builder type infantry are what Infantry Sections and Sappers are, which is why they are effected by the aura. However, since Commandos aren't units you can build emplacements with, they were not given the builder type.
We see the Commandos receive the same icon change that other British Infantry get when in the Lieutenants range. They are clearly supposed to benefit from it but they don't. We weren't able to see it before because Stens used to be powerful weapons. But now it can be seen clearly that they don't benefit at all.
Come on guys! The Commandos aren't considered overpowered anyway. Ask any player who play the British without bias and they will tell you that Commandos suck vs vetted infantry. It's time that this bug is fixed. After all, they would lose their power again after you kill the fragile Lieutenants, so I don't see this causing balance problems.
YurdleTheTurtle found various other bugs and fixed them with his mod. Here's a like to his changelog. I request that you guys look at the bug fixes in particular. Did you guys know that the Jagdpanther gives you less experiance when killed than a Jeep does?
