Anime where the MC joined the army and killed some orphans Hi, I'm searching for this Anime where this particular scene happened:  
The MC (or his friend maybe?) was shooting at helicopter. He and his friend were running from enemies in the field of grass.  
At the end his friend stayed behind and dead. The MC succesfully escaped tho.  
After that or before that, MC and his squad found out that the enemy organization were hiding orphans. His team then killed all the childern there with guns.  


thanks for the help! was searching for this anime this past week but couldn't remember what
