well... Technically speaking, the eggs ARE their periods.Do they lay eggs like once a month, or daily like chickens? If they‘re on their periods then do they add that special ketchup to their omelets? Do they even have periods? I need answers…
Now that's a stupid strategy. Seriously, what the point of him being in the frontlines? He's a resource supplier and engineer, not a combatant. If the enemy learns a countermeasure against his weapons, what difference will it make placing him on the frontlines?
He's the main provider of basically everything: food, water, shelter, weapons, armor, tools, comfort, technology,seed, etc., putting him on the front line means risking him dying and losing all the advances they've made so far. Let's not forget that they had NOTHING to defend themselves with before the arrival of the MC.

You literally just answered yourself: He provides EVERYTHING.
With him on the front line that means quick resupply/arming of everything.
Need weapons? Crafted
More bombs? Right away.
Need a fort? Plop one in the chapter.
Heck he's probably carrying a whole supply camp's worth of stuffs in his inventory.
And yes they know there's risk of him dying, what do you think that part with Danan and Leo was about? They knew there's risk but they still want to basically deploy the mobile fortress for that supply carrying/immediate crafting access.
