No, addicted is an adjective... a word that modifies a noun. It still isn't an action.
If there are no studies or other mental health professional opinions, then what you're saying is quite frankly a load of crap. It's the opinion of a combat EMT that is biased towards the situation. Now, as far as asking soldiers... one of my best friends from high school has spent about 75% of the last 8 years in Iraq and Afghanistan... he's a 19K (gun operator) on an M1A1, and served in that capacity in Iraq. He's now in Afghanistan operating light armor (since heavy armor is relatively non-existent there). I know for a fact that he has no issue expressing his feelings, while still performing his job duties at a very high level. I have another friend that was Marine infantry in Iraq for nearly his entire 4 year career... the same thing goes with him about expressing his feelings. Those two are quite possibly the toughest SOBs I've ever met.
I have another friend that was in the Navy, ooh big deal you might say... except for the part where he made it through the the INDOC period of BUD/S, made it through hell week, but finally had to ring the bell after three straight days of being nearly too sick to walk. He decided not to go back a second time because at that point he had met his future wife and decided being a SEAL wasn't for him if he wanted to have a family. Again, he's one of the toughest people I know... no problem expressing his feelings.
Finally, a family friend of mine was in Iraq at 19, already an E-4, stationed at Forward Operating Base Kalsu. During a mortar attack, he had the courage and balls needed to not only save the lives of his men, making sure that they got to safety, but also a group of Iraqi civilian contractors that were scared shitless and couldn't move because of it. Right as he got them to safety, a third mortar hit and he was killed by the shrapnel from that blast... he was posthumously awarded the Bronze Star with Valor. I didn't know him well... but he was a lay pastor at the age of 16, before enlisting in the Army... I heard him speak on two separate occasions, and he also had no problem expressing his feelings... and paid for his courage and valor with his life.
Perhaps you understand the point by now... being able to express your feelings, even in a group setting, doesn't make you a pussy, nor does it make you psychologically weak... it makes you human.
