01' Davy Crockett was quite a guy. He built up a reputation as a topnotch woodsman and a crack shot, and in those days you could only build a reputation one way- by performance. 01' Davy delivered the goods. Of course, some of his pals might have been stretching the truth just a little bit when they claimed he killed himself a b'ar when he was only three years old . It might be hard to say just how old he was when he threw down on old Bruin for the first time, but he sure killed a lot of em after that. And it didn 't matter if it was a four -legged or two-legged varmint that tangled with him- he knew there was only onc way of taking care of 'em. He knew he had to have good weapons, in good conditi on, and with a good man behind them. Talking wouldn't do it. The only way men like Davy Crockett kn ew they were going to have meat on the tab le- and get back home to eat itwas to kn ow their gear and know that iLwould perform. True sights- preservative oil - dry powder-clean weapon - good flint - clean, true ammo- most of the things a frontiersman kept his mind on are the same things a good sol di er checks on today, Just like he and his pals might have said: " It just don't make no diffrunce"- if you're wearing a coonskin hat or a steel helmet, if you're using a flintlock or your trusty M 1, if you're rid ing a flop -eared jackass or an M4 8- oil in the right place, cloth on the dirt, tightening and check ing right along, all will help see that you get there, get the job done and get back. For you or for Davy Crockett, Preventive Maintenance still means the same thing- you'll get performance when the chips are down.

(Para 176,c,4 TM-9B19A, Page 257). Then, of course, you 're ready for the road test. You make this just like it tells you in the TM also, (Para 176, e. pages 259-260).
