Oh I am going to have fun with this. Teddy Roosevelt quotes, all.
"It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."
"A man who is good enough to shed his blood for his country is good enough to be given a square deal afterwards. More than that no man is entitled, and less than that no man shall have."
"Thrice happy is the nation that has a glorious history. Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows neither victory nor defeat."
"There should be relentless exposure of and attack upon every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful."
"Don't hit at all if you can help it; don't hit a man if you can possibly avoid it; but if you do hit him, put him to sleep."
*sigh* I have to point out that despite what you see in games, lasrifles win wars. Just because lasrifles suck at killing superhuman killing machines in power armor does not mean that they are bad weapons. You are shooting them at the wrong targets. The most common enemy the Imperium faces is lightly armored humans armed with lasguns or autoguns, NOT SPACE MARINES.
