hey dogplasma: my time in the army we just used the 3 section bars.the last time i was issued them the foil packs were tan in color and not o.d. lately i've been buying the smaller 1section bars i find now at gun shows etc..also the bars will turn to powder if exposed to air for along time.. even if they apper to be brand new items open the box they come in and inspect them for quaility.. .get what you pay for.....vince. <img src="images/graemlins/smile.gif" alt="" />
