Having missed FH1 (and WW2, some rhetoric may have changed since then), some comments:
"MARS MARS" -- this is missing the mandatory latter part, "SAA SUORITTAA!". Also, "LIIKETTÄ", what happened to "LIIKKUU"? "JAKSAA JAKSAA" anyone?
"SUOJAUTUKAA!" -- quite literal, usually it was "SUOJAAN!". Speaking of which, "ILMAVAARA!" should then be "PAREMPAAN SUOJAAN!"
"PYSYKÄÄ TÄSSÄ!" -- how about "JÄPITTÄÄ!"
Also the generic term "vihollinen", implying there would be Lapland War ever implemented. Oh well, at least one of the soundbites used "naapuri".
Bonus points for "Tuu veljyyn" though.
(SA-INT's law: when at least two Finnish men are gathered either online or IRL, conversation will inevitably turn to Army reminiscence sooner rather than later.)
Since I bothered to look up FH1 vidyas:
"Tämä selvä" -- cf. "Sain."
"Heti raapas" -- W.T.F.? Not "ÄITIII!" or "VITTU MUA SATTU!"? (At least there was one "PERKELE!". Definitely needs moar PERKELE! Though "Ei helvetti" was OK too.) "Vasen lapa", nice quote, "Kymmenen vuotta turhaan", another WTF?
