Nails and mortar! Nails and mortar! Yells abound as such things are needed at a construction site. nails for wooden boards and mortar for them brick walls. Nail aand mortar!!!
And then there is nail and mortar of a different sort: mortars and nails, mortars and nails! and you throw nails into the mortars, they go THUMP and them nails fly high, onto the enemy ranks.
but serious man use special grenades or maybe rockets for their mortars.
I just read a book about war in Angola in the seventies, and on the MPLA side there was a single garrison way deep into the south, where they had two mortars and two portuguese partisans would fire them without tripods, from their very own hands, burning themselves seriously in the process.
