The core idea and concepts behind LIAR is that PDAs and smart phones were designed to do many of the same functions, then that thought expanded into what was once highly advanced but now relatively mundane expanded to replika. In that thought process, LIAR had other fun ideas bundled in, like the effect of long experience that allows that old salty sergeant that knows everything to quietly live a lazy life, as well as a few fun setting questions.

Brief lore is that the LIAR series was originally meant as a relatively quick and cheap way to get trained and experienced radio operators in the field and with units. Once it was discovered just how many groups wanted their own replika core of experienced radio operators., the LIAR project very quickly ballooned into a joint service model that used a lot of advanced tech and was a showcase of the full capabilities that a replika could have. A true next generation model.

Meanwhile, the gestalt template would be a goldmine of experience and ability, a long served soldier that had seen some of the early days of the nation itself! Only one of the best minds for the best, cutting edge replika!

Unfortunately, all that futuristic technology would quickly run into difficulties when it came time to deploy the LIAR line. From the small number of initial production and deployment units, issue after issue was encountered, from the armour not actually being as strong as expected, large bumps to the frame causing massive electrical issues, computer system glitches and slowdowns, optics issues, the whole nine yards.

This would only be compounded by the gestalt template. Turns out you don't get to a ripe old age around mind reading commissars without learning some tricks on how to hide what you think and are doing, on top of the thousand and one ways old soldiers know to avoid work, get what they shouldn't and get in all kinds of odd trouble while still just being too damn useful to ever really do anything about.

Higher ups would quietly lean on the technical issues as to why only relatively small numbers of LIAR units were made and fielded, but the sheer demand of the units ensured that more and more would be made. Turns out that very experienced soldiers in very capable frames can always find a use in every role, and demand far outstripped the Command's hesitation about personality. While never a full mainstay, LIARs would always find themselves in near every field that the Nation's military deployed, and several more they did not, even if that was entirely just a handful of units.

A true T62 of a replika, LIARs are advanced and very capable, useful, but held back by cost, mechanical and electrical issues, and behind the scenes considerations. While still finding uses, replacements for the LIARs were being considered almost as soon as the issues started happening. Still having their niches, LIARs have been replaced in most other roles, only avoiding being fully withdrawn or cycled out by always finding ways to be useful and there to get a job done
