covering fire

• Ammo bearers either provide cover fire for the gunner / a - gunner ( if in contact or under fire ) or pick up any spare ammunition at the site of the gun ( if the situation allows for it - do not grab the ammo if it means you ' re going to get shot doing so )
  送弹员可以为两位抢手提供火力掩护（如果已经与敌人接触或是已经遭到进攻） ，或者整理机枪边还未使用完的弹药（如果情况允许? ?不要试着去拾子弹如果这样做意味着你将挨子弹） 。
