Read the lore, retard. The Imperium needs 1–6 weeks to cross a handful of light years on a “stable” warp route — and that’s the good outcome.
The bad ones are 2 minutes, 1,200 years, or never arriving at all.

EXCERPTS ON WARP TRAVEL

Notes of Sharim Calypso, Adjutant advisor to the Imperial Navy. Ref. MCS17-82h.57c

The Questio Logisticus branch of the Adeptus Administratum has a division devoted to tracking median travel via common warp routes. Although only two millennia worth of data has been compiled, it has thus far proven little, save what is already known – to enter warp space is a deadly and unpredictable risk.

By way of an example, note the logbook of the Proxxian traders that operate in the Nephilim Sector. They primarily transport forced labour, from the hive world of Proxx to the isolated mining colonies of Hephastian, approximately three times each Terran year. The distance is dozens of light years and requires a fleet to traverse the immaterium. The route is anything but predictable, despite being classed as a semi-fluctuating passage (the most stable rating). Typical voyages range between one and six weeks, but the more extreme journeys have taken as much as 1,200 years and as little as two minutes. Some 22% of expeditions have, as of yet, not arrived at their destination – although given the time disparity, one can only estimate what percentage have been lost and which are still en route. In distance, this is a relatively short voyage; the numbers only grow worse with longer journeys.

>Marines destroy baseline human meatbags unless they're lucky enought to get a shot with a heavy/special weapon

A fucking Marine got his throat punctured by a wooden spear and died.
And you’re seriously trying to argue a plasma blaster to the head wouldn’t kill him?
