Even if others are in the front lines while you're stuck with the veterans in back, do your duty where you are. Use your voice, your encouragement, your example, and your fighting spirit. Even a soldier with both hands cut off can still help his side win — if he holds his position and cheers on his comrades. Do the same thing yourself. If fortune pushes you back from the front ranks, stay where you are and keep cheering for your side. And if someone silences you completely, then stand there anyway and help your cause through quiet action.
Even though others may form the first line, and your lot may have placed you among the veterans of the third, do your duty there with your voice, encouragement, example, and spirit: even though a man's hands be cut off, he may find means to help his side in a battle, if he stands his ground and cheers on his comrades. Do something of that sort yourself: if Fortune removes you from the front rank, stand your ground nevertheless and cheer on your comrades, and if somebody stops your mouth, stand nevertheless and help your side in silence.
